Drain pineapple; reserve syrup. Blend syrup, soy sauce, honey, sherry, orange peel and garlic powder in large bowl; stir in ham cubes. Cover; refrigerate 1 hour, stirring occasionally.
Cut each bacon slice crosswise in half; wrap pineapple chunks with halved bacon slices.
Thread bamboo or metal skewers with a wrapped pineapple chunk, an olive, another wrapped pineapple chunk, a marinated ham cube and a cherry tomato.
Place skewers on rack of broiler pan; brush with marinade. Broil 3 to 4 minutes on each side, or until bacon is crisp. Typed by Syd Bigger.
