I'm worried about this, too, but I usually eat rice for two days, pancakes for two days and noodles for one day. So there are only two people in my family. Generally, only one dish is fried, such as eggs, tomatoes, lentils, Jiang Dou, diced vegetables, cauliflower, broccoli, rape and spinach, which is enough for one week. When it comes to Saturday and Sunday, we usually go out for a party at noon. If I don't have to cook, I can have a mixed meal at night.
