Drain chicken on a wire rack set over a pan in a slightly warm oven.
Add a tablespoon or so of oil to a large, clean pan and cook the onions and peppers for a minute.
Add the sauce to the pan and simmer until thick enough to coat a spoon, or just a little thicker...
Add sauce to chicken to cover. [NOTE: There might be quite a lot of additional sauce. Store to use over other recipes.
Stir quickly to coat.
Garnish with toasted sesame seeds or almonds and additional bits of green onion if so desired.
