@darius I would guess some “mid-century” microwave cuisine/freezer foods would be easy places to watch. TV Dinners have mostly already changed forms and the “classics” are disappearing/only remain for nostalgia; I’ve seen frozen Salisbury steak “patties” directly on hipster menus like liver and onions used to show up/our generation’s shared frozen foods childhood meatloaf nightmare; maybe even some “big” things like pizza rolls or Pop Tarts don’t survive long term.
