Marinate the chicken: Get out a medium-sized bowl and add both the chicken and all of the marinade ingredients. You a spoon to mix it all up, until a batter is formed and it coats every piece of chicken. Set this in your fridge to marinate for 30 minutes to two hours.
Make the sauce: Get out another medium-sized bowl and add the sauce ingredients to it. Then use either a whisk or a fork to mix the ingredients together.
Fry the chicken: Pour a ½ inch layer of oil into a walled pan/skillet and place it over medium-high heat. Once the oil is hot place the chicken pieces into the oil making sure that it’s not overcrowded and no pieces are touching each other. Shallow fry the chicken pieces in the oil for about 5 to 8 minutes, or until they have become golden brown and crispy. Take the fried chicken pieces out, place them on some paper towels, and set them aside.
Stir fry the aromatics and vegetables: Clean the pan/skillet that you were using, pour 1 tablespoon of oil into it, and place it back over medium-high heat. Toss in the garlic, ginger, green chilies, and green onions, sauteeing the ingredients for 1 minute. Then toss in the onion and bell pepper and continue to sautee everything for 2 more minutes.
Finish the dish: Pour the sauce into your pan/skillet and stir so that it coats the vegetables and aromatics. Let the sauce come to a low boil then toss in the fried chicken. Stir until the sauce coats every piece of chicken.
Pour the chili chicken onto a plate, garnish with extra green onion, and enjoy immediately.
