Grilling fruit caramelizes it for a crisp and sweet outside and a warm and tender inside. It also brings out the natural sweetness, so no added sugar is required! Try it as an appetizer, a side dish, or a dessert with your next barbecue.
Combine all ingredients except chicken in a medium bowl, mixing well. Add chicken, cover with marinade, and cover the bowl. Refrigerate for 2-24 hours.
Grill chicken on an outdoor grill or on a stovetop grill pan, flipping once nice grill marks have formed, until internal temperature reaches 165° F, or finish in oven once both sides have nice grill marks. Another option is to bake at 350° F until internal temperature reaches 165° F, about 20-30 minutes, depending on the thickness of the chicken.
