Prepare the chicken according to your grill type and your preference. (For me, as I’m intending to grill as a whole, I just transferred the fillets out from the packaging into a large container.)
Combine all the marinade ingredients in a bowl and mix them well. Pour the sauce over the chicken. Mix evenly to coat the chicken with the sauce. Cover and marinate it for at least 4 hours or overnight in the fridge to deepen the flavor.
Grease the grill plate and preheat the bbq following your grill manual. Grill the chicken, covered for 5-7 minutes per side, or until the chicken is cooked through. (An inserted thermometer should read 165 degrees F / 74 C). If you have opted, grill some rice cakes and sweet potatoes. Be sure to coat them with some cooking oil before placing them on the grill.
Serve. (Refer to my serving suggestions in the main post!)
