Pizzas prepared on the grill are truly summer delicacies. I love topping grilled pizza with different meats and sweet and sour ingredients, a winning combination for everyone! And in this particular recipe, the tangy kick of BBQ sauce takes the flavor up a notch. I topped this pizza with pieces of chicken, bacon and mushrooms; however, adding a few plums would no doubt delight guests that like a little more 'sweet' in the balance of sweet and sour flavors. What would you serve alongside this tasty pizza?
