Ooh, OP, this is a lovely thread. It’s making me hungry with so many tasty sandwich recipes to try.
I think most anything can go on most any bread! I don’t eat meat or fish but am up for trying most things on - or wrapped in - any bread. I don’t really have a favourite. (One thing I won’t eat is Heinz sandwich spread - nope, a definite turn off for me. I’m not keen on Branson pickle either but will suffer it if need be but it would have to be the finely chopped version.)
I love good old crisps on bread. Cheap date me, what? 😂
Mash potatoes, optional other stuff mixed in - any veg, esp sprouts with a smidgen of salt and lots of black pepper; a bit of gravy, stuffing, Yorkshire pud if any is left. Yum.
Stuffing butty just on its own, any time, any place, any bread. A great culinary delight.
Pie - oh, squashed cheese and onion pie - or quiche - on bread, ketchup optional.
Salad - just mixed salad, or cucumber and / or tomatoes. Piccalilli / mayo / salad cream optional but salt and ground black pepper is a must.
Sliced or crumbly cheese and onion / tomato, cold or toasted. Crumbly cheese can get a bit messy though, dropping out of the bread…
Marmite, with or without cheese but I’m going to try it with cucumber now - thanks saltrock123 for that suggestion.
Banana - sliced or squashed, esp on toast but nice on any bread. I may have tried it with marmite, too and quite liked it…
Jam on bread - when I have a yearning for something sweet.
Oh, I’m really hungry now.
