Season chicken with salt, pepper and garlic powder; set aside.
Heat a pan or skillet over medium high heat; sear chicken thigh fillets or breast fillets on both sides until golden and cooked through.
Reduce heat after searing on both sides, cover skillet with a lid and continue cooking until the chicken is cooked through, while turning every 5 minutes until done. Alternatively, see notes for oven method.
Drain most of the excess oil from the pan, leaving about 2 tablespoons of pan juiced for added flavour.
When chicken is done and cooked through, arrange chicken skin-side up in the pan (if cooking with skin); add the garlic between the chicken and fry until fragrant (about 30 seconds). Add the honey, water, vinegar and soy sauce. Increase heat to medium-high and continue to cook until the sauce reduces down and thicken slightly (about 3-4 minutes).
Garnish with parsley and serve over vegetables, rice, pasta or with a salad.
