Do you know why people will eat meat over legumes?
I mean, is this a human thing? A social thing?
I'm not sure the science is in on it, but it does seem to have a biological component. Meat pushes neurological buttons, same as fat and sugar do. But in Europe, it's also, and majorly, a social thing. Look at e.g. India or CHina for comparison. Europeans have been conditioned over generations that a "real" meal includes meat, unless it is specifically one designed to be abstemious. Being a vegetarian in a Europeanb culinary context is ridiculously difficult (one reason why so many vegetarians turn to non-European cuilinary traditions).
