Not that I'm vegan, but I found this very interesting. Love the lentil/steak comparison at the bottom. I'm a meat eater, but have cut back to a few serves a week, rather than at dinner every single night. Definitely keen to keep doing this and eventually reduce my overall meat intake to a minimum, substituting foods like chickpeas, lentils and toful for protein.
