If the landlord wants to do it himself, buy some electrical appliances from Bear's house. I think the electric steamer is very good, and there are fried eggs. The landlord can fry an egg in the morning, and then steam some steamed buns with a glass of milk. It is best to drink less soy milk because it is hard and difficult to digest.
LZ can also make some fruit salad as a side dish or steamed egg soup, both of which are nourishing to the stomach.
