Preheat oven to 400°. Line jelly-roll pan with aluminum foil. Combine 2 tablespoons Wish-Bone® Italian Dressing with tomatoes in pan; shake to coat. Roast 15 minutes or until tomatoes are tender and just beginning to burst.
Meanwhile, combine broccoli, onion and 2 tablespoons Dressing in large bowl; set aside.
Arrange spinach on serving platter. Top with chick peas, broccoli mixture, warm tomatoes and cheese. Just before serving, drizzle with remaining 1/4 cup Dressing. If desired, sprinkle olives.
