Oyakodon Craving

I have a sudden craving for oyakodon (chicken and egg mixture on rice).....huge craving......which I cant satisfy coz there is dinner at home.
I bought some mirin from taka though.....just in case the ILs decides to go away again for the weekend....*fingers crossed*
This is one of the more promising recipe I found online. Will attempt to try it sooon.

Oyakodon (4 servings)

4 cups cooked rice, keep warm
4 chicken thigh fillets or 2 chicken breast fillets
1 onion
2 cups dashi stock
10 tablespoons soy sauce
5 tablespoons mirin
5 tablespoons sugar
4 eggs

1. Cut chicken in small chunks, slice onion
2. Put the stock, soy, miron and sugar in a pan and simmer for a few minutes.
3. Put chicken chunks in the pan and simmer on low heat for a few minutes
4. Add the onion to the pan and simmer for a few minutes more
5. Whisk the eggs in a bowl
6. Bring the soup back to the boil, pour the eggs over chicken and onion
7. Turn the heat to low and cover with a lid
8. Turn the heat off after 1 minute
9. Divide the hot cooked rice between 4 bowls then place the chicken mixture over the 4 bowls of rice

Note: it will probably taste better if the ingredients are divided and cooked individually. At least thats how they do it in Japan....which reminds me....I need to go get one of those japanese flat pans for making this. A small saucepan or flat frying pan will also do if the high class tools of trade cannot be procured.
