With all this attention to how destructive a meat-based diet is to the animals, ourselves and the planet, I've not paid a whole lot of attention ( online anyway ! ) to all the really fabulous food that far outshines what corporate animal ag wants you to know !! So here's a few great sites to get an idea of "what to eat" :)
Chooseveg.org has a number of cooking videos featuring Colleen Patrick-Goudreau from Compassionate Cooks.
Vegetarian Resource Group has lots of recipes and solid nutritional information for the entire family.
The Vegan Diet site is a veritable encyclopedia of food !
Compassion Over Killing not only works tirelessly behind the scenes to relieve animal suffering, the also have a nice cache of recipes and ideas on how to go veg, including a great Vegetarian Started Kit.
