1. Combine spices in a small bowl. Strip the leaves from the lower half of each rosemary sprig to make a skewer. Thread shrimp onto skewers. Brush shrimp and tuna steaks with olive oil then coat with spice mixture. 2. Heat stove top grill or gas grill to high heat. Place shrimp on grill and cook 2-3 min. per side until opaque. 3. Place tuna steaks on grill and cook to desired doneness, turning once. Cook 2 min. on each side for rare center; 3 to 5 min. each side for medium center; 5 to 8 min. each side for well-done center.
