Balsamic BBQ sauce:
1 cup balsamic vinegar
3/4 cup ketchup
1/3 cup brown sugar
1 garlic clove, minced
1 tablespoon Worcestershire sauce
1 tablespoon Dijon mustard
1/2 teaspoon salt
1/2 teaspoon freshly ground black pepper
Combine all the sauce ingredients in a small saucepan
until all the ingredients are incorporated and the mixture is
smooth. Simmer over medium heat until reduced by 1/3, about
15 to 20 minutes.
Place a grill pan over medium heat or preheat a
gas or charcoal
grill. Season the meat with salt and pepper. Lightly coat with some
of the BBQ sauce using a pastry brush. Place the meat on the grill.
Place the remaining BBQ sauce, still in the small saucepan, over
low heat or on the edge of a gas or charcoal grill and allow to
gently simmer while the meat cooks.
Cook the chicken about 8 minutes per side. Continually
meat with BBQ sauce every few minutes. Remove the meat from the grill
and let rest for at least 5 minutes. Serve with the heated BBQ sauce
