Recommend a dish, "Tofu Stewed with Tomato", which is very simple. This dish was originally invented to treat children's anorexia, but I think it should also be suitable for adults, and I have successfully treated one of my classmates' anorexia with this dish! I hope it will help your friends, too! The specific method is as follows: old tofu 1 block (about 1 kg) is diced for use, 3 tomatoes are cut into small pieces for use, and pepper, garlic and salt are appropriate. Pour a little oil into the pot first, then put pepper to squeeze it out, be careful not to squeeze too much; Then take out the pepper residue and throw it away; Then stir-fry the tofu with the oil in the pot. After the tofu skin turns golden yellow, pour in the chopped tomato pieces, stir-fry quickly, and pour in half a bowl of water after the tofu and tomato are fully contacted, and start stewing. After about five minutes, add minced garlic and salt, let it stand, and serve. Be careful, don't use fire. The specific temperature should be mastered by yourself. I think a small fire is enough.
