Noodle soup is the most common soup in the north, especially in winter. After eating the staple food, the whole family will sit around the table and have a bowl of hot soup, which is called a whole body comfortable, warm stomach and cool. This one I made today is especially suitable for old people, women and children. Although there is no meat and shrimp, it is nutritious, delicious, digestible and full, and can play a role in losing weight. The main ingredients of pimples are flour, vegetables and eggs, and the colors are red, green, white and yellow, which makes people have an appetite. If it is thin, it can be regarded as soup; if it is thick, it can be used as a staple food. It can be eaten as breakfast or as an emergency dinner.
