I've been cooking community dinners for nearly 50 years, including, for most of that, for vegetarians/pescatarians/vegans. I even was camp cook on 4 week-long raft trips.

It never fails: someone wants a fake turkey, or fake bacon, or fake burgers, or whatever. Unwrap the plastic, heat it up, it sez on the label it's vegan. Also you omnivores are killing the world.

So I now refuse absolutely to cook for vegetarians/vegans. I always did make somebody else buy the fake industrial vegan meat substitutes, and amazingly, I caught friction for that. My wife and I are chemical engineers who have been inside quite a few food processing plants and we refuse to touch the output of those. I will eat potato chips every once in a while but nothing vegan at all. I want my vices honest.
