The back of a package of Upton’s chorizo seitan says “vegan & plant-based”. I’ve talked with a couple people about this before: plant-based isn’t inherently vegan, but there are only a very select few implausible ways to get food that’s (varying degrees of debatably) vegan and not plant-based. We’re talking, like, accidental roadkill, a hamburger you found in the trash, an animal killed in a dire survival situation… (Edit: Okay, I guess pure salt as a meal also applies.)

So Upton’s, I’m really glad you reassured me that it’s both.
