There are several materials to consider:
Millet, rice, mung beans, red beans, red dates, lotus seeds, tremella, oats and barley.
These materials can be bought in supermarkets, but don't buy more at once, because insects will grow if you don't have a refrigerator for a long time, but it will be fine if you are cold. Soak the ingredients for 5-8 hours before eating, and the soaking time can be extended in winter. After soaking, add water to boil. It takes a little longer to cook beans and coix seed, maybe 1 hour is enough. Therefore, it is recommended to use a small rice cooker (probably the kind around 40 yuan).
You can mix all these materials at will. If you want to eat sweet, put rock sugar, salty, and put some salt. If it is convenient to buy food, you can also make an egg porridge, which saves time and money.
Is to dice the vegetables (cut as conveniently as possible) and cook them with rice.
Cook until you think it's ok. Beat an egg and mix well. The eggs will come out right away. Add salt and oil (according to your preference) and start eating. One of the most concise recommendations is egg and tomato porridge. Delicious and slim. Remember that eggs are put in last.
By the way, if it's too long, you can simply buy several kinds of rice to cook in one pot, purple rice, black rice and millet. Soak for an hour before cooking.
