Plain, frozen vegetables are better buys than frozen vegetables packed with sauces. Purchase resealable frozen vegetables in larger quantities so that you can use only the amount needed for one meal. Depending on seasonal costs of fresh vegetables, frozen and canned vegetables may be the best buy. They can also be stored longer than fresh vegetables. For example, a large beef or pork roast can be served as a roast, and used later in the week for stew or soup.
Large turkeys are usually a better buy because the flesh to bone proportions are better.
After roasting large turkeys, cut meat from the bone so that you have enough for a turkey dinner. Remaining turkey can be repackaged and frozen in amounts that can be used in casseroles, pot pies, or sandwiches. The turkey carcass can be put back into a stew pot for the beginning of turkey soup. When it comes to baking, save some energy costs and economize your time by baking many items in one session. Double batches of many baked goods will allow some to be repackaged, frozen and used at a later time.
