No man wants to always go to his parents' house for dinner. You should understand him.
You can cook some meat on weekends, such as stew, ribs and a chicken, and then put it in the refrigerator. Buy some vegetarian dishes at noon and take them home from work at night. You can go home and heat the meat, stir-fry a vegetarian dish and make an egg seaweed soup or something. That should be enough. You can also ask your parents to stew it for you, and you can take it home in time. Or wrap some jiaozi and put it in the refrigerator. Cooking at night is convenient. In short, we should base ourselves on doing a good job in life.
