Honestly I think Beyond Meat/Impossible style burgers are aimed at meat eaters who want to reduce animal cruelty/their carbon footprint. It’s actually kind of annoying they’re so popular now, as restaurants that used to have creative vegan options now sell Beyond Meat as the only choice.
Vegans don’t tend to care if a veggie burger is “realistic”. Some find the idea of meat gross and don’t want to roleplay eating it (my wife says they make her feel sick). Even if you don’t mind, the longer you give up meat the less interesting it is as a flavor. I’d take one of those shitty frozen veggie burgers that are 90% potato over an Impossible burger.
