I don’t necessarily mean specific recipes, I mean concepts. A western sandwich is bread, (vegan) meat or cheese, sauce, tomato, something pickled, some salad, mostly, all layered and/or thinly sliced. Cross out maybe some of them for simplicity, like the mayo tomato or the british cheese and cucumber.
A döner kebap is sort of layered but everything but the protein layer is more of a mix up and not like tomato followed by onion or whatever.
A Banh Mi is sort of western of course, but it does a twist. The layers are there-ish, but they don’t matter so much. Sort of a hybrid between something like a kebap and a pita if you catch my drift.
What other sandwiches are there, conceptually?
a lasagna is not a sandwich because it does not have the carbohydrate on the outside to grab and help eat but otherwise yes, we’re getting somewhere here. How do I edibly glue them fries together for that fry-bread sandwich?
We deep fried a couple sheets of lasagna noodles at work so they were like chow mein noodles but big and square and then put lasagna stuff in there and ate it like a sandwich
Yes! Yes!!
Frybread actually means something fully different from fried X as a sandwich; it is vaguely like naan but with more oil.
the answer to this and all spiritual/existential questions is the same:
mayonnaise.
baked mayonaise sounds more like a bandname than a culinary technique so elaborate here
