Sprinkle chicken with lemon-pepper. Grill over medium-hot heat or broil 4-6 inches from the heat for 15-18 minutes or until juices run clear, turning once. Set aside and keep warm. Drain pineapple, reserving 2 tablespoons juice (discard remaining juice or save for another use); set pineapple aside. In a jar with a tight-fitting lid, combine oil, soy sauce, vinegar, honey, ginger and reserved pineapple juice; shake well. Brush some of the dressing over pineapple; grill or broil for 2 minutes. Cut chicken into strips. Arrange vegetables on serving plates; top with pineapple and chicken. Sprinkle with peanuts, if desired. Serve with remaining dressing.
