Foods that aren't claimed to be somehow native to the Americas.
Idk about gourmet, I've honestly never had explicitly high end Mexican. Just side of the road trailers and mama y papa restaurants, but damn if it wasn't good. You might make decent to great Mexican, I dunno; if we're ever in the same area I'd love to find out, either way (I doubt you make TexMex if you care at all about heat and quality of the dish).
