Combine the ingredients for the sauce in a small bowl and set aside.
Season the chicken with salt and pepper and toss to coat. Using a large pan, heat the oil over medium heat. Once the oil is shimmering, add the chicken and evenly space. Allow to cook for 3 minutes or until the edges begin to turn white. Use tongs to turn each piece of chicken and cook for another 3 minutes. Toss again to cook on all sides. The chicken should be crisp and cooked through to 165 F.
Add the sauce and scrape the bottom of the pan to remove any burnt bits on the bottom of the pan. Allow the sauce to come to a simmer and cook for 2-3 minutes or until thick. Toss to coat the chicken.
