DO-AHEAD TIP: Marinate chicken for 30 minutes (see recipe).
In a medium bowl, whisk together the first 6 ingredients (olive oil through garlic); transfer to a large zipper-topped plastic bag. Add chicken, seal bag and shake well to coat; refrigerate for 30 minutes.
Meanwhile, place salsa, black beans, onion and cilantro in a saucepan over medium heat; cook and stir until heated through and onion becomes soft, 5 to 7 minutes.
Preheat oven broiler. Remove chicken from marinade (discarding marinade) and place on a lightly oiled baking pan; broil for 7 minutes per side or until juices run clear.
Serve chicken with black bean and onion salsa mixture and garnish with desired toppings.
