Buy a home "cryovac" machine like food saver. Prepare cooked meals such as pasta sauce, stews, curry etc in meal size portions. Cryovac and put in the freezer. To use them put, still in their sealed bags in hot water and bring to the boil. You can do things like boiled, mashed rosti potatoes. Frozen beans, peas, broccoli etc can be portioned out into separate bags (either at use time or in advance). It doesn't matter what combination you choose to use, they are all in separate bags in the same pot of water. The range of meals is only open to your imagination.
