At my house, we'll often cook double what we need for dinner, dish up the extra meals and freeze them on plates ready to go.

Every now and then on a good day I'll have a cooking day. I might bake a pie, cook a couple of casseroles, including one in the slow cooker, maybe make a pizza, and I'll make some pasta sauces for freezing. We always have enough in the freezer for around a week, and I assure you they get used.

Pay some-one to do it for you if you think it would help.
