Ketchup, hoisin sauce and soy sauce create the aromatic Asian-inspired sauce for this quick-to-fix grilled chicken recipe.
Heat gas grill to medium-high or prepare charcoal grill with medium-hot coals.
In a small saucepan, stir together ketchup, hoisin, soy sauce and sesame oil. Cook over medium-high heat until bubbling, about 5 minutes. Remove 3 tablespoons sauce from pot and set aside.
Lightly coat grill with nonstick cooking spray or oil. Place chicken thighs on grill bottom-side up and baste with sauce. Close grill cover and cook 5 minutes. Remove cover and flip thighs, basting generously with sauce. Continue brushing with sauce every 5 minutes for about 20 minutes or until internal temperature reaches 160° on an instant-read thermometer.
While chicken is cooking, stir together reserved sauce, broccoli slaw, vinegar and salt and pepper. Refrigerate until ready to serve.
