In small bowl, combine soy sauce, brown sugar, ginger and garlic powder;
mix well. Place chicken on plate. Brush both sides of each breast
half with soy sauce mixture. Cover; let stand 15 minutes at room temperature
to marinate. Heat grill. When ready to grill, oil grill rack. Place
chicken on gas grill over medium high heat or on charcoal grill 4-6
inches from medium high coals. Cook 8-10 minutes or until chicken
is tender and juices run clear, turning once. Top each with pineapple
slice during last few minutes of cooking time. Serve sprinkled with
coconut.
