Your list is interesting too -- I'd have claimed steak as a moderately right-wing food. Though it sorta depends. Filets, NY Strips, and Rib-eyes are pretty neutral, but T-Bone and Porterhouse steaks are more right-leaning.

Certainly, anything "intentionally vegan" is a left-wing food.

Chicken seems to be consumed by most everyone (as are eggs).

Anything with tofu or other soy product (except soy sauce) is probably left-wing unless it is a dish from a region which has historically used it (especially if the tofu is a substitute for meat) -- so, for example, Agedashi Tofu is politically neutral, as is something like Mapo Tofu, but an Americanized sweet and sour tofu would be a little bit left, and any kind of "tofu steaks" or anything where the soy is a meat replacement is farther-left.

Avocado is very slightly left. But, if you spread it on a toast with eggs, radishes, and microgreens making an Avocado Toast, it's now far-left.

There's all kinds of really interesting nuance out there on the subject of partisan foods.

Generally I think of whisk(e)y as having like all brown liquors, if anything, a bit of an elitist vibe but not really a left-right association.
