Add marinade to chicken and make sure all pieces are evenly coated. Marinate for at least 4 hours, but its better the longer it marinates. I didn't put all of the marinade on the chicken, and saved some to serve over rice!
Grease a non-stick skillet and heat over medium-high heat. Add chicken and cook, on each side for approximately 5-6 minutes. Be sure you cut into a piece of chicken or use a thermometer to check temperature, depending on the size of the thigh it may take longer.
Also note, the sugar in the mango will begin to caramelize, its not burning, it will get crispy and delicious!
Served with brown rice and sauteed kale with onions.
