This review covers both "Betty Crocker Easy Everyday Vegetarian: Meatless Main Dishes You'll Love" (2006) and the older "Betty Crocker's Vegetarian Cooking: Easy Meatless Main Dishes Your Family Will Love" (1998)
I like the Betty Crocker vegetarian recipes because they use readily-available ingredients and are generally simple to make, yet are still creative and tasty. They're also great for households with both vegetarians and non-vegetarians, since many can be modified to accommodate both. The recipes are also likely to appeal to non-vegetarians.
Some people complain about the use of a lot of canned and frozen ingredients, but it's not that hard to substitute the equivalent from scratch if you want - cooking dried beans instead of using canned beans, fresh vegetables instead of frozen, etc. However, the point is for the recipes to be easy and approachable. It's not Moosewood or Vegetarian Times, but it doesn't try to be. I don't mind making my own tomato sauce or cooking dried beans - but sometimes I just want quick and easy.
The reason for mentioning both books in this review is that it isn't really clear from the titles or descriptions whether they're different books or different editions of the same book, so hopefully if you already have one of the books or are wondering about the difference, this information will be useful.
There's a large amount of overlap in recipes between the two books - about 35%, especially in the soups, sandwiches, pizzas, and casseroles. The older book has more salad and side-dish recipes, plus some muffin/scone recipes. The newer book has more appetizers, and a lot of recipes that use soy protein nuggets/patties/crumbles as meat substitutes--in fact, there's a whole section on soy. If you like to use that sort of product, the newer book might be more appealing, but since I don't, I find the older book has many more recipes in it that I'd use, and I give it a slight edge over the updated version.
