Cut the chicken into bite size pieces
Slice your onions thinly.
Prepare your sauce and set aside.
In a heated pan, add some oil. Saute the onions until they are slightly wilted. Then add in the chicken.
Stir fry the chicken for 3-4 minutes until most of the pink colour is mostly gone.
Add in your sauce and cover. Let it simmer for 10-11 minutes until the sauce is thickened.
Fry an egg (optional)
Serve the chicken on rice with your fried egg, kimchi (optional), lettuce or cucumber, nori and sesame seed seasoning (optional).
