While there are many, many recipes on the web, sometimes I just like to stick with my favorite cookbooks. Almost all of these books are for vegetarians.
Better Homes and Gardens New Cook Book
The best all purpose cookbook I've ever encountered. Every recipe seems to turn out the way it should (even when one doesn't follow the directions precisely). I tend to use the bread and dessert sections the most. It also has lovely cheat sheets for ingredient substitutions and cooking times for various grains and beans.
Better Homes and Gardens Best Bread Machine Recipes
This came bundled with my Better Homes and Gardens New Cook Book. The recipes are good but I usually have to tinker quite a bit to make them come out right in the bread machine. It probably doesn't help that I'm at a fairly high altitude.
Favorite Brand Name vegetarian Cooking
In general I distrust recipe books with pretty pictures. It seems like they spend too much time on the pictures and not enough on the recipes. However, this book is an exception. It has pretty pictures and usually ends up tasting good too.
This is the book I pull out whenever I feeling extra healthy.
Lean and Lucious and Meatless
This book tends to be a bit healthier than many of my other recipe books. Plus they provide nutritional information for each recipe.

Vegetarian Cooking for Everyone by Deborah Madison
This is my new favorite cookbook. Every recipe is wonderful.
