I've heard about Chipotle Mexican Grill. We don't have them here in Alberta, but they are a fast food Mexican restaurant in the U.S. and they are working on providing healthy, local food in a fast food venue. They buy some of their meat from Polyface Farms which is owned and operated by Joel Salatin - a man whose most recent book, "Folks, This Ain't Normal" is currently on my bedside table. It's wise and totally what I believe in:
Other books you should read: "In Defence of Food" by Michael Pollan; "Animal, Vegetable, Miracle" by Barbara Kingsolver.
Let's remember what's important and how fragile our gigantic system actually is.
