Preparation:

Jerk Rub: Blend all rub ingredients in a food processor fitted with steel blade. Rub jerk seasonings over chicken. Place chicken in a shallow bowl and refrigerate 2 to 4 hours. Chicken: Spray a grill rack and adjust it on grid over ashen-hot coals. Put chicken on rack. Cook about 10 minutes, turning once or twice as needed. Grill until chicken is cooked through but not overcooked. While chicken is grilling, cook the pineapple. First sprinkle it with lime juice and a small amount of brown sugar. Grill pineapple about 2 minutes on each side. Pineapple should be hot. Serve chicken hot with a slice of grilled pineapple. Note: Jerk rub originated on the island of Jamaica. The rub is a spicy combination of flavors used to enhance the taste of meat and chicken during the marinating process. Here it is used as interesting flavor combinations for the chicken.
