• 1 lg. onion, thinly sliced
• 1 Tbs. plus 1 tsp. olive oil, divided
• 2 garlic cloves, minced

• 8 oz. fresh mozzarella cheese, thinly sliced
• 2 plum tomatoes, cut into 1/4-in. slices
• 1/4 C. sliced ripe olives
• 2 Tbs. capers, drained

In a small skillet, saute onion in 1 Tbs. oil until tender. Add garlic; saute 1 minute longer. Remove and keep warm. In the same pan, cook arugula just until wilted; remove and keep warm.

Brush one side of each pita with remaining oil. Layer with cheese, tomatoes, arugula, onion mixture, olives and capers. Grill pizzas, covered, over medium heat for 2-4 minutes or until cheese is melted. Serve immediately.
