Combine the first 7 ingredients in a large dish with a lid. (I used a 9x13 pyrex dish) Then add the chicken. Cover and refrigerate for 2 hours, up to overnight.
Heat oil over medium-high heat in a large skillet. When the oil is hot, add the chicken to the pan (reserving the marinade) and brown it on all sides.
Stir in water and reserved marinade and bring to a boil. Reduce heat; simmer, uncovered, until chicken is no longer pink and sauce is slightly reduced, 20-25 minutes.
Serve the chicken topped with cooking sauce, sesame oil, sesame seeds and green onions.
