Mix juice, sugar, vinegar, oil and Seasoning in small bowl with wire whisk until well blended. Place fruit and vegetables in large resealable plastic bag or glass dish. Add marinade; turn to coat well.
Refrigerate 30 minutes or longer for extra flavor. Remove fruit and vegetables from marinade. Discard any remaining marinade. Alternately thread fruit and vegetables onto skewers. Lightly sprinkle with additional Seasoning, if desired.
Grill over medium heat 10 to 15 minutes or until vegetables are tender, turning frequently.
