I personally combine toast/taco/bowl because the boundaries are far too vague, they're essentially the same thing. Flatten a taco, and now it's a toast? Nonsense! It was toast all along! Same with that soggy-bottomed quiche that can't support itself or its family! And then I add "nacho" as its own top-tier category instead of some weird optional DLC at the end, i.e. "bread surrounded by non-bread". So you have calzones and anti-calzones. Croutons in salads count as soup / nacho / anti-calzones, as do (non-filled) noodles of effectively all kinds - they're all bread with stuff on the outside. Which brings us to the logical conclusion that the world is a nacho.
