Unusual but delicious sandwich fillings

[Lougle]

I had a cheese sandwich today and had run out of pickle. So I scanned the pantry and decided to try a bit of mint sauce. Delicious!

What other fillings am I missing out on?

Cheese and salad cream

Cheese and apple

Baked beans. According to DM.

Cheese and marmite, though that's not super rare.

Bolognese sauce. Need to time it right, and it's messy, but spoon some on buttered bread and fold it over whilst dinner is cooking. Yum 😋

Chicken fajita mix in a sandwich with guac.

Sweetcorn, spring onions & mayo

Hummus, grated carrot and rocket
Cheese and marmite
Blue cheese, pear and celery

Ok so this is totally normal in the States but each time I make it for someone here they recoil like I've spread dog food inside bread:

Peanut butter, and mini white marshmallows dotted thickly over. Can tear up jumbo marshmallows if needed.

I know Fluff can now be bought here but I'd love to know what the Brits are doing with it, if a PB + Marshmallow sandwich is madness.

I put leftover saag paneer on thick sourdough the day after an Indian takeaway.

Cheese and mango chutney
Ready salted crisps and mayo
cold roast potatoes and some sort of hot sauce

Peanut butter with dates or banana. Raisins work too.

Tuna and coleslaw

Tomatoes, mayo and tiny bit of hot sauce.

chicken super noodles, grated cheddar

These are great. I'm not a fan of very wet fillings, so I'd have to modify some of them.

I love the idea of the blue cheese, pear, and celery combo.

Cheese and chutney. Sausages and marmalade. Any sort of pate

Jam and cheese
Peanut butter and jam
Ham, egg, lettuce, tomato & red onion

@BluebirdBoogie I know what I'm having for lunch tomorrow! Yum

Halloumi and gherkin

Banana

Thick-cut (preferably freshly carved) ham, with crisp, firm green/white seedless grapes (halved).

Bacon with Brie

there used to be a 'posh' sarnie shop that did avocado and cashew nut sandwiches on seeded bread. So delicious but I've never managed to exactly replicate them.

I like an onion bhaji in a sandwich, with salad leaves and mango chutney. The bread has got to have a bit of heft to it though, none of yer nasty plastic white sliced.

grilled:
sharp cheddar, sauerkraut, and red pepper jelly

Shamelessly placemarking

Another vote for cheese and apple, usually Granny Smiths and cheddar

@CocoapuffPuff Have you tried peanut butter and cucumber? In brown bread ,its heavenly

Corned beef, red onion and tomato ketchup

Tuna, salad cream, chopped celery and grated red leister

Second pp saying cheese and mango chutney (Brie is best for this imo)

Smoked salmon and horseradish sauce (can be mixed with cream cheese like Philli)
