For the Chicken, mix marinade, jalapeno and cilantro in medium bowl. Place chicken in large resealable plastic bag or glass dish. Add 1/2 cup of the marinade mixture; turn to coat well. Refrigerate 30 minutes or longer for extra flavor.
For the Salsa, mix beans, mango, tomato, onions and 2 tablespoons of the remaining marinade mixture in medium bowl; toss lightly. Set aside. Remove chicken from marinade. Discard any remaining marinade.
Grill chicken over medium heat 6 to 7 minutes per side or until cooked through, brushing with remaining marinade mixture. Serve chicken with Black Bean and Mango Salsa.
