I like to go to amazon.com and read the customer reviews. They've helped save me more money! And I've always liked the items I've gotten there with the best reviews. My crock pot is the primitive OFF/HI/LOW kind, so I'm no help there.

However, snork maiden, for vegetarian crock pot cuisine I recommend The 150 Best Slow Cooker Recipes by Judith Finlayson. It does have meat recipies in it, but it also has

Appetizers and Fondues
Soups (many are vegetarian or convertable with vegetable stock)
Beans, Lentils and Chilies (also, convertible to vegetarian)
Fish, Seafood, and Vegetarian Favorites
Vegetables
Desserts

It's the only slow cooker cookbook I recommend, the recipies are fabulously yummy.

There's also two or three veggie crock pot recipies in our recipe section.

Good hunting, gals!
