Trim fat off chicken and dice into bite size pieces. Set aside.
In a bowl, whisk together the marinade ingredients then dump into a ziptop bag. Add chicken and squish around until fully coated. Marinate in the fridge for 30 minutes to 2 hours.
Heat a large skillet over medium high heat. Remove chicken from bag and reserve marinade. Add chicken to the skillet and cook until caramelized, about 2 minutes. Flip and cook the other side another 2 minutes, or until cooked through. If skillet gets too dry add a bit of the reserved marinade, making sure to heat it through to cook away the raw chicken.
