Wash, clean, and cut up chicken into 1" pieces.
Add all ingredients to the chicken except the cornstarch and oil. Mix well and marinate at least 1 hour.
Cut up vegetables and set aside.
Add ingredients for the sauce (up to apple cider vinegar) in a small pot and heat on medium heat until boiling, then add cornstarch mixture while stirring for about 2 minutes until slightly thickens. Remove from heat.
When ready to cook, place cornstarch over chicken and toss until all pieces are covered.
Heat a large skillet on medium-high heat, add oil, when hot , fry chicken 2-3 minutes and turn , fry another 3 minutes.
Move to plate. Repeat process until all chicken fried.
When ready to serve, add the onions and sweet pepper to sauce and heat about 1 minute. Place chicken into the pot of sauce and stir to coat all pieces.
* If chicken needs to be re-heated, place in a air fryer or toaster oven before adding to sauce.
I recommend this dish with white rice. But any side of choice will go well.
