- Heat oil in a frying pan over medium-high heat.
- Cut chicken into 1½-inch chunks, season with salt and pepper and allow to sit for about 5 minutes before sprinkling cornstarch. (The salt will pull out the chicken’s natural juices and create a batter with the cornstarch.)
- Fry chicken in single-layer batches until golden brown. Cool on paper towels or cooling rack.
- Stir in remaining ingredients in a bowl and heat in a wok or wiped-out frying pan. Once it boils and thickens, add cooked chicken pieces and toss to coat.
- Serve with steamed rice and garnish with green onions.
