2. Preserved vegetable rolls are also a good choice, mainly using Chinese cabbage, bean curd skin, dried mushrooms, salt, boiled mushrooms, clear oil and monosodium glutamate. Wash the Chinese cabbage, blanch it in a boiling water pot, take it out, drain it and chop it up. Cut the tofu skin into four parts. Water-soaked shiitake mushrooms and dried shiitake mushrooms also need to be boiled in boiling water, fished out and cut into filaments, and then put the shiitake mushrooms, Chinese cabbage and dried shiitake mushrooms in a big bowl. Add a proper amount of salt, clear oil and monosodium glutamate, stir evenly, spread bean curd skin, put a proper amount of vegetable stuffing into each slice, roll into strips, put them on a plate, and steam them in a cage for about five minutes.
