Directions

1. Coat grill rack with nonstick cooking spray. Preheat grill to medium (300°F to 350°F). In a large bowl combine bread cubes, basil and garlic. Drizzle with 2 tablespoons of the oil; toss to coat well.
2. To assemble skewers, thread 1 bread cube, 1 tomato and 1 onion chunk onto each of 8 skewers.* Repeat once, finishing with a third bread cube. Brush skewers with remaining 1 tablespoon oil.
3. Place skewers on grill. Grill, covered, 5 to 8 minutes or until bread is lightly toasted, turning once or twice.
4. Place lettuce leaves (if desired) on 4 salad plates. Top with skewers, drizzle with pesto, and serve.
