Identify your food based on the location of structural starch. Is a hot dog a sandwich? No, it’s clearly a taco.
This analysis has an inconsistency regarding pie:
A slice of pumpkin pie is listed as toast (starch on one side), but a slice of double-crusted pie is a taco (three sides), a whole key lime pie is a quiche (five sides), and a whole double-crusted pie is a calzone (six sides).
In all cases save one, side crust is seen as distinct from bottom crust. A slice of pumpkin pie therefore has starch on two sides, making it a sandwich.
Except that the sides are adjacent, so it would be a taco, wouldn’t it?
Edit: On further reflection, I think that the designation of “bent toast” is just too much of a slippery slope given possible malformations a food could undergo leading to morphology changes. This is the whole problem with morphological naming schema. It’s carcinization all over again.
