Cut chicken into 1-inch cubes. Toss chicken in batches with cornstarch, tapping off the excess. Set dredged chicken on a platter lined with kitchen towel and set aside.
1 ½ pounds chicken thighs, ½ cup corn starch
In a separate dish, combine all the ingredients for your sauce and whisk to combine.
3 tablespoons low sodium soy sauce, 1 tablespoon rice vinegar, 1 tablespoon hoisin sauce, 2 tablespoon granulated sugar, 1 tablespoon cornstarch, ½ cup cold water
Preheat a non-stick skillet with oil. Cook chicken in 2 to 3 batches, sauteeing until golden on both sides and cooked through then remove the chicken from the pan and transfer to a bowl. Repeat with the remaining chicken, adding more oil as needed. Leave at least 1 tablespoon oil in the pan.
½ cup extra light olive oil
Add the garlic, ginger and pepper flakes. Sautee for about 30 seconds or until fragrant.
1 tablespoon ginger, 1 tablespoon garlic, ¼ teaspoon red pepper flakes
Add the sauce to the skillet and bring it to a simmer while stirring. Let it simmer for 1 minute to cook off the vinegar a little. Taste the sauce and add more soy sauce or rice vinegar to taste if desired. Add the chicken and toss to coat. Serve garnished with sesame seeds and green onions if desired.
1 teaspoon sesame seeds, green onions
