2. Buy a small rice cooker. Bear brand is good. There's one with a frying pan and a steamer. The main pot can cook noodles, hot pot, snail powder and so on. The frying pan can fry eggs, cakes and dumplings. You can buy frozen ones in the supermarket. If the supermarket has that kind of dish, you can buy a small portion of this frying pan for cooking. Steamed corn, steamed bread and purple potato can also be bought in the supermarket. Buying this kind of small pot with quick-frozen food, vegetables and eggs in the supermarket can meet a person's dietary needs most of the time, without using kitchen utensils such as chopping boards and kitchen knives. Every time I buy less, the refrigerator can still be used. However, it is recommended to buy a mini refrigerator, which is more convenient to use.
