This is a dish made with fresh, simple, Chinese and Western methods. It tastes a bit like French fries, but the oil is much less than the French fries.
Washed and peeled potatoes
Heat a small amount of oil in the wok, pour in the potato slices and stir fry evenly. Add water to cover the potatoes (you can add more water to the soft-faced potatoes), and cook until the water is basically juice.
Stir in a small amount of salt, then pour in the tomato sauce and fry until thick. Finally, you can also sprinkle with black pepper to taste.
Out of the pot, sprinkle with black pepper powder is ok.
