Most lists of sandwich fillings are written for home lunchboxes. This one is different. We make sandwiches for a living, supplying shops, cafes, schools and offices across England and Wales, so we see the sales numbers behind the recipes: which fillings sell out by noon, which ones need the right shop to work, and which ones look clever on paper and die on the shelf.
Here are 40 sandwich filling ideas that have earned their place, grouped by the job they do in a chiller or on a platter. Use them to refresh a menu, plan a buffet or argue with a colleague about coronation chicken.
No apologies for starting here. These ten fillings outsell everything else combined in almost every shop we supply, and any range that skips them is leaving money in the till.
1. Egg mayo. The quiet bestseller of British lunch. Soft, seasoned, on white or malted bread. Ours is a permanent fixture for a reason.
2. Tuna mayo. Close behind egg in every chiller. Generous mayo, firm bread, no surprises.
3. Tuna mayo and sweetcorn. The upgrade path from plain tuna, and a favourite with younger customers.
4. Chicken mayo. Plain-sounding, endlessly bought. The measure of a sandwich maker, because there is nowhere to hide.
5. Chicken and bacon mayo. The biggest seller in many of the shops we serve. Smoked bacon makes the difference.
6. Ham salad. Proper deli ham, crisp lettuce, tomato, a little mustard mayo if you are feeling generous.
7. Cheese and pickle. Mild cheese, tangy pickle, the fixed point around which British sandwiches rotate.
8. Cheese and onion. Sharper and simpler than pickle. Splits the room, sells regardless.
9. Cheese and spring onion. The softer, fresher take on cheese and onion, and our own long-running favourite.
10. All day breakfast. Egg mayo, sausage and bacon in one sandwich. Sells in the morning, sells at lunch, sells to anyone who missed breakfast.
These fillings sit one step from the classics: recognisable enough to trust, interesting enough to trade up to. They are where a chiller starts building personality.
11. Cheese ploughman’s. Cheddar, pickle, salad, a nod to the pub lunch. A steady premium seller.
12. Ham, cheese and pickle. Two classics merged. Bigger, better, slightly dearer.
13. Chicken salad. The lighter counterpart to chicken mayo. Summer’s dependable seller.
14. Cheese and tomato. Simple, vegetarian, and a toastie waiting to happen. Our Toasties range does exactly that.
15. Cheese and red onion. Sweeter than white onion and prettier in the pack.
16. Cheese coleslaw. Crunchy, creamy and underrated. Works in a salad box as well as a bap.
17. Deli ham and cheese. The continental double act. Reliable in sandwiches, stronger still grilled.
18. Tuna melt. Tuna mayo plus melted cheese: the toastie that built a thousand cafe menus.
19. BLT. Bacon, lettuce, tomato. When the bacon is right, it never needs reinventing.
20. Prawn mayo. The classic that behaves like a premium line. Weekend and treat-day sales.
Spiced fillings are the biggest shift in food-to-go over the last decade, and the shops we supply confirm it weekly. These are the lines that stop a chiller looking like 1995.
21. Chicken tikka. Britain’s favourite curry, cold in a sandwich. A top-five seller in most convenience shops.
22. Chicken tikka with yoghurt and mint. Our chicken tikka and mint pairs the spice with a cooling raita note. Better balanced, better reviewed.
23. Honey chilli chicken. Sweet heat sells. Our Honey Chilli Bird is proof: it is one of the first lines new stockists reorder.
24. Chicken shawarma. Street food gone mainstream. Our Algiers chicken shawarma brings North African spicing to a wrap that sells across every age group.
25. Spicy drip chicken. Heat with juiciness rather than dryness. A signature seller from our premium range.
26. Peri peri chicken. The flame-grilled flavour customers already know. An easy introduction to the spiced shelf.
27. Sticky kick chicken. Sweet, sticky and hot in one bite: a bagel filling that earns its name.
28. Merguez sausage and cheese. Spiced North African sausage, melted cheese, halal friendly. Distinctive and increasingly asked for.
29. Butter chicken. The mild curry option for customers who want flavour without fire. Works in bagels, wraps and pasta pots alike.
30. Chinese chicken. Hoisin-style sauce, crisp vegetables. A takeaway flavour at a sandwich price.
The test for a meat-free filling is simple: would someone who eats everything still choose it? These pass. Every chiller needs at least two of them, and platters need more.
31. Smoked roast pepper falafel. Our smoked red pepper falafel is the vegan line that meat eaters buy. Smoky, satisfying, nothing worthy about it.
32. Cheddar cheese salad. The vegetarian staple done properly: mature cheddar, fresh salad, honest bread.
33. Egg and cress. Old fashioned and unbeatable on a buffet. The first platter quarter to disappear at a wake or a works do.
34. Hummus and roasted vegetables. Colourful, vegan, travels well in a wrap.
35. Mexican bean. Spiced beans, salsa, a little crunch. The vegan option for the spice shelf rather than the salad shelf.
36. Coronation chickpea. Coronation chicken’s vegan understudy, and increasingly the star. Curried, creamy, familiar.
37. Cheese and coleslaw salad box. Meat-free and hearty enough to be lunch. Our Salad range exists because not every lunch wants bread.
Premium fillings do not sell the most units. They do something better: they lift the perceived quality of everything beside them, and they win the customers who would otherwise walk to a coffee shop. Our Signature range lives here, and we explained the thinking in What Makes a Sandwich ‘Signature’?
38. The deli stack. Layered deli meats, cheese, salad and dressing on quality bread. The sandwich that photographs well and sells itself. If customers want to find premium sandwich recipes with real deli character, a muffuletta-inspired version is a good addition: briny, hearty, and built to leave a lot of impact.
39. Ham salad on a tiger French stick. The bread does half the work. Crackled crust, proper ham, a sandwich that feels like an occasion. For a quick premium lunch, roast beef also earns its place here: filling, often requiring two hands, and substantial enough to justify the spend.
40. Honey fire melt. Sweet heat and melted cheese in a toasted format. The premium toastie for cold months and bold customers.
Knowing what not to stock saves as much money as knowing what to stock. A few patterns from years of sales data.
Anything that needs explaining dies in a chiller. A filling with a three-line description sells at farmers’ markets, not forecourts, because the grab-and-go customer makes quick decisions and needs to find the filling immediately understandable. Wet ingredients without structure fail too: fillings heavy on tomato or cucumber against soft bread turn sad by 11am unless the recipe is engineered for it, with wet ingredients layered between dry elements to prevent soggy sandwiches, which is precisely the kind of detail a manufacturer obsesses over so a shop does not have to.
And beware the owner’s favourite. The range exists for your customers, not your palate. If the till data says plain chicken mayo outsells your beloved brie and grape four to one, the chiller has spoken, and no personal preference is any good unless it sells. Home-style sandwich recipes do not always survive retail chillers.
The list above is not static. Salads, lighter wraps and chicken salad lines earn extra facings from May to September, then hand them back to all day breakfasts, melts and toasties when the weather turns. December belongs to festive specials: turkey, stuffing and cranberry variations sell for six weeks and vanish without regret.
The rhythm matters because regulars are your volume. Someone who buys lunch from the same shop four times a week sees your chiller two hundred times a year, and a range that never changes teaches them to stop looking. Two or three rotating lines against a stable core of classics keeps the display familiar and fresh at the same time, which is exactly the balance the big food-to-go chains spend millions maintaining.
If you run a shop or cafe, pick a spread rather than favourites: six or so classics, three familiar twists, at least two spiced lines, two meat-free options and one premium flag-bearer, then let a month of sales data make the next decision. If you are building a buffet, the same balance applies in platter form.
Two final rules of thumb from the production floor. First, bread choice changes a filling’s fortunes as much as the filling itself: the same ham salad sells differently on white, malted, a bap or a tiger French stick, so vary the carriers as well as the contents. Second, names sell. “Honey Chilli Bird” outperforms “sweet chilli chicken” on the same recipe, because a name that promises personality gets picked up first. Neither trick costs a penny, and both show up in the till within a fortnight.
And if you want any of these made fresh and delivered to your door, that is the day job. We build tailored ranges for retailers through our Bespoke service, and the full current line-up is in our online shop, where you can find the wider collection.
