Why would anyone ever pick just one type of ethnic food????? One of the joys of being vegan is that there are so many ethnic options that are not meat-based!

You've already gotten good web resources about going vegetarian. If you eat a balanced diet, and don't become a coke and potato chip vegetarian, you'll be fine. The book that changed my life is Diet for a New America by John Robbins; it's doesn't have recipes, but goes into detail about the beef, poultry, dairy, etc industries.
