I almost forgot how to do it..
Step1:Cut potatoes, cut mushrooms, cut thick slice
Step2:Put the garlic and ginger slices in the oil and stir fry the potatoes until the potatoes cry. Then put the mushroom slices in the soy sauce and sprinkle with pepper (pepper or fennel or cumin is not powder, anything is OK. Give the same thing. This dish doesn't give spices, because there is no meat). Add a little water and cover the pot and burn. When it's all soft, put salt in the pot and sprinkle with scallion.
