Preheat oven to 325 F.
Spray a 9" x 13" baking dish with non-stick spray.
Put cornstarch, salt and pepper into a large resealable baggie. Seal and shake to combine.
Add chicken to the baggie and seal and shake to coat well.
Put beaten eggs into a small pie plate or bowl.
Heat some of the oil in a large skillet over high heat.
Working in batches, shake some of the excess corn starch off the chicken then place into the eggs. Rotate to coat, shake off the excess, and place into the hot skillet.
Cook chicken 1-2 minutes per side until golden. You are not trying to cook the chicken completely, just get a nice color and bite.
Remove chicken to the baking dish, spreading it out in one layer.
Continue until all of the chicken is browned, adding more oil if necessary.
Whisk together all of the sauce ingredients and pour over the chicken.
Bake for 45 minutes to an hour, stirring and flipping the chicken every 15 minutes, until the chicken is done.
Serve over warmed rice garnished with green onions.
