This pita pizza recipe can also be made on the grill, which is perfect for summer nights. Preheat the grill to medium (about 375-400°F) and brush both sides of the pitas with olive oil. Grill until marked, about 2 minutes per side. Remove from the grill and add your toppings. Return the pitas to the grill, cover and cook for 3 to 5 minutes until the cheese has melted. Easy-peasy!
