1. Peel and cut potatoes into small pieces, soak in water to remove excess starch; wash and slice tomatoes
2. Heat oil in a pan, add tomatoes and stir-fry until tomato juice appears, set aside
3. Heat oil in a pan, add potatoes and stir fry for a fragrant flavor
4. Put the fried tomatoes and potatoes together, add ginger slices and some water and cook until the soup turns red and the potatoes soften. Add some salt to taste.
