Marinate chicken with seasoning ingredients for several hours.
Heat 1?2 tablespoons oil in a heavy-based frying pan. Panfry the chicken pieces with the skin side down for 2?3 minutes over a medium heat. Flip over and fry the meat side for 3?4 minutes or until just cooked. Dish out.
Heat remaining oil in a clean saucepan. Add garlic and fry till fragrant. Put in mushrooms, onion and combined sauce ingredients. Fry briskly for 1?2 minutes. Add peas and fry for an extra minute. Dish out and serve with the pre-fried chops. Serve immediately.
