My family is vegetarian, we eat only natural whole-foods. If you eat this way you will find it alot cheaper than centering each meal around meat. Also much better for your health. Stay away from processed, convenience foods. Buy fresh fruit and veggies for snacks.
Several cookbooks publish low-fat salad dressing recipes.
These are easy to make and a lot cheaper, not to mention, better tasting. Cook with nonfat dry milk. You can also substitute a white sauce made with nonfat dry milk and water plus the appropriate seasonings for recipes that call for condensed creamed soup. Purchase lowfat hotdogs, bacon, and kielbasa in bulk when they go on sale. Freeze the excess.
