I see a lot of people at least joking about going vegan lately. I've been vegan for roughly.... ah, I want to say 4 years now? I lost track awhile ago. It was around the time the wreckers came to Hexbear and convinced a bunch of us to watch Dominion (highly recommend doing so btw, it's free online).
ANYWAYS, if you're interested in more than just shitposts and are seriously interested in veganism I was thinking I could help answer any questions you have. Comment here or send me a DM if you're blush shy. 
This comm has limits on what we can talk about btw, such as diet. And I think the whole website has restrictions on recommending specific brands of food? So DM for questions like that, thanks.
I mean lots of people are particularly allergic to peanuts and those are vegan. What do you mean by vegan foods specifically? Because vegan food can mean anything from an apple to an Oreo cookie. Do you mean meat substitutes?
Usually meat substitutes are made of soy, wheat, beans, potato, mushrooms, jackfruit, or some combination of starches/gluten. So if your allergies cross over with any of those I'd suggest looking into the ingredients on a meat substitute to figure out where you need to watch out.
What I'd honestly suggest though is moving away from meat substitutes entirely. There are a lot of great cuisines that don't rely on using meat, dairy, or anything similar!
Yeah, meat substitutes like nuggets, the sort of shit you'd grab from the frozen aisle. I'm a prep cook in my day to day so I rarely have the energy to cook at home as much as I love to cook.
