Man where were you 8 years ago when I ate zero protein because I didn’t know it could be cheap. Couldn’t afford animal products and was conditioned to believe those were the only viable source of protein.
Btw I’d like to add textured vegetable protein to the list! It’s one of my go-tos nowadays.
Where I live it is, because of local-ish soy production. Also helps that it’s a complete protein, so you don’t have to think as much about which amino acids you’re getting from where.
