Bean burritos or tostadas with low-fat cheese. Even nachos made with baked chips can be the main dish – just don't tell your kids they are healthy!
Vegetarian lasagna. Instead of meat, use eggplant, other vegetables, tofu or soy crumbles.
Veggie burgers. Forget the drive-thru when you need a quick meal. Many frozen vegetarian burgers can be popped in the toaster or microwave.
Spaghetti with tomato sauce and soy crumbles. Soy crumbles can be purchased frozen, and TVP (a dehydrated soy product) can be bought at health food stores. They are both great substitutes for ground beef.
