I think I started pre-Quorn when you had to go to a 'health food shop' for sossmix and stuff. Linda McCartney helped change things for the better.
Makes me laugh when some blokes say eating meat makes them more manly when the nearest they came to hunting was stalking Tesco. As for drinking cow's milk, that's for babies :)
I laugh at that too. A guy I work with almost only eats meat and scoffs at the idea of eating vegetables. He is never off the toilet and has the unhealthiest complexion you could ever imagine!
We used to buy those soya chunks that you had to rehydrate yourself. They were nice but it was a fine art to get them in the sweet spot between crunchy and soggy!
