Whisk together all the sauce ingredients in a large bowl. Set aside.
1/3 cup soy sauce, 3 tablespoons brown sugar, 1 tablespoon rice vinegar, 1 tablespoon chili garlic sauce*, 1 tablespoon ketchup, 2 teaspoons sesame oil, 1 tablespoon cornstarch, 2 cloves garlic, 1 inch ginger, 1/4 teaspoon red pepper flakes
In a large shallow bowl, whisk together the cornstarch, salt, and pepper. This will give the chicken that signature crispy texture.
1 cup cornstarch, 1 teaspoon salt, pinch of pepper
Dredge the chicken pieces in the cornstarch mixture. Shake the excess cornstarch off the chicken. Then, transfer the pieces to a large plate.
1 1/2 pounds boneless skinless chicken breasts**
Heat the oil in a large skillet over medium heat. Once heated, use tongs to transfer the chicken to the skillet. Working in batches, fry the chicken for 3-4 minutes per side until golden brown and crispy. Overcrowding the pan can lead to soggy chicken. Give the pieces space so they get that golden crust. Transfer the chicken to a sheet pan lined with a paper towel.

Drain or wipe the excess oil from the skillet. Add in the sauce and let it sizzle for a minute until thickened.
Turn off the heat, stir in the chicken pieces, and toss to coat them in the sauce.
Serve the chicken over rice and sprinkle with chopped green onion, and sesame seeds.
