1.
Cut the bones of the chicken legs into small pieces, then marinate them with salt, pepper, mirin, and starch for 5 minutes.
2.
Heat the pan with a little oil and low heat. Put the chicken drumsticks down and fry until the color changes. 
3.
Add the chopped onion cubes, add mirin, soy sauce, soup, add boiling water (to cover the chicken cubes), cover and simmer for about 10 minutes. The onions should be softened.
4.
At this time, the soup is about half the height of the chicken nuggets. Pour in the beaten eggs evenly, and then cook until the eggs are about to be cooked. Pour the whole on the rice (the bowl should be large, and the dish must be covered completely. Live meal, and then eggs. Actually, it depends on personal preference. Some people like to cook them more when they are older, and cook them for a while if they are tender.) Put some coriander to look good, but if you don’t put it, you don’t like coriander.
