Chicken and Egg Rice Bowl (Oyako don)

Such a beautiful day.
After I made my children busy by spending the day with their friends, I stood in the kitchen as always. 
Chicken and Egg Rice Bowl (Oyako don)
This is quite popular and classic Japanese dish.
How to cook this?

It’s very simple.
You just simmer the chicken and onion in the sweet soy sauce soup, then add the beaten egg.
And put them onto the rice.
​Just it. 

My children made smiles with full mouth.
Their happiness makes me smile.
