Cut rice cakes into slices and soak them in hot water to soften and set aside. Then, cut onions, carrots, green peppers and other vegetables into small pieces and sauté them in a wok until cooked. Next, add the rice cake slices and the right amount of chili sauce, salt, sugar and other seasonings, and continue to stir fry evenly. Finally, add an appropriate amount of water and cook until the rice cakes become soft and flavorful.
