Normal people cook their own food with restaurant meals being an occasional treat.

This. I will go out to eat when I cant be bothered to make something, but that is usually once a week max, once every other week more often.

For my normal week, when I go grocery shopping, I will buy meat (usually switch it up between chicken, pork chops, or burgers), cook it on the weekend when I have plenty of free time, and then put it in the refrigerator in a container. Sometimes with extra food like potatoes that I also cooked. Then throughout the week, when I get home from work, I just get some of the meat and other sides like carrots, and that will be dinner.
