There are a lot of women out there who view not being able to cook as some kind of feminist flex. This goes all the way back to when Bill Clinton was running for office and Hillary Clinton said she wasn't going to be one of those wives who "baked cookies all day." Never mind the fact that every person, regardless of sex, should pick up some cooking skills, as there are few things more important to a person's well being than what they stick into their mouth. No wonder we're such a nation of fatasses. The food you buy at a restaurant is almost guaranteed to have twice as many calories in it as the food you'd make for yourself at home, as the restaurants want you to come back in and get more food - that's why they prioritize its tastiness over it's health properties...
I keep a steady supply of rice and pasta on hand, simply because they go with everything, even prepackaged sauces/meat. You don't have to go full scratch when making every meal.
Buy one of those giant chubs of lean ground beef and you can use that to make a ton of dishes. I occasionally make a stew using 1lb of cooked ground beef, a chopped up onion, a can of vegetable beef soup, a can of cream of celery soup, and chopped up potatoes (boiled until they're soft.) Toss all of this into a casserole dish and bake for an hour. It tastes great and will feed about 4-5 people.
