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 classic from college:
Thus, the sandwich is Western in form (bread/sauce/cheese/other/cheese/sauce/bread), but the layers cohere to produce an irreducible whole apart from its components. The sandwich has the portability required for every occasion from the boardroom to the discotheque while maintaining a utilitarian, even proletarian, character. And it contains enough preservatives that if you made 1000 of them today you’d survive through Judgment Day.
