Combine Chicken and Marinade ingredients in a bowl. Marinate for at least 20 minutes, or up to overnight.

Heat 1 tbsp oil in a skillet over high heat. Remove chicken from marinade (reserve marinade) and place in the pan. Sear both sides until browned - about 1 minute on each side. Do not cook the chicken all the way through. Remove and set aside

Heat the remaining oil in skillet. Add garlic and onion, cook 1 1/2 minutes.

Add the reserved marinade, water, sugar and black pepper. Bring it to a simmer then turn heat down to medium high. Simmer 5 minutes.

Add chicken smooth side down. Simmer uncovered for 20 to 25 minutes (no need to stir), turning chicken at around 15 minutes, until the sauce reduces down to a thick jam-like syrup.

If the sauce isnt thick enough, remove chicken onto a plate and let the sauce simmer by itself - it will thicken much quicker - then return chicken to the skillet to coat in the glaze.

Coat chicken in glaze then serve over rice. Pictured in post as a healthy dinner plate (415 calories) with cauliflower rice and Ginger Smashed Cucumbers.
