any other vegetarians????

I am a vegetarian and I don't know a lot about meatless substitutes - anything that resembles meat is out of the question for me - just a picky eater. because of this I tend to eat a lot of pasta, breads and rice....which my doctor recently suggested I eat less of. So I am working on finding more healthfull choices that I will enjoy. Anybody have any suggestions that would be great - any good recipies????
