Oyako-don (chicken and egg with rice)

I made this for my bf’s lunch a while ago, and it was good :)
What you need
2-3 boneless chicken thighs
1 large mild onion sliced thinly
1 cup instant dashi
4 tsp sugar
¼ cup soy sauce
2 tbsp mirin
4-6 eggs, beaten
¼ cup peas, thawed

How to
Slice the chicken diagonally cut into 1-in lengths. Place the onion, stock, sugar, soy sauce and mirin in a saucepan, bring to a boil. Add the chicken, cook over medium heat until the chicken is cooked (about 5 minutes). Skim any scum off the sauce. Ladle a quarter of the mixture into a frying pan and bring to a boil. Pour a quarter of the egg over the mixture in the frying pan, sprinkle with a quarter of the peas. Cover and cook over medium heat until it’s cooked. Then slide the cooked mixture onto the rice :)
