Here are some solutions.

If you don't have a lot of freezer space, go buy one. You can get a model that holds a lot of food and is the same side as a kitchen chair. Costs about the same as a week's worth of pizzas.

It takes the same amount of time to cook ten portions as it does to cook one. I like to make a huge pot of chili or stew or soup and freeze it in pint size containers. Five minutes to cook in the microwave. A big pan of lasagna will give you a dozen meals. Or you can cook a whole roast chicken on Sunday and eat it all week. Chicken and rice on Sunday, chicken tacos on Monday, green salad with chicken on Tuesday...
