Pita with Tomatoes, Olives, and Parmesan

All the flavors of summer come together in this simple open-face pita sandwich. You can add thin strips of red and green bell peppers or halved yellow pear tomatoes, too. Also, be sure to wash the arugula thoroughly, as it can be sandy, or you can buy bagged, cleaned arugula. If arugula is not your jam, watercress or mixed baby greens can be used instead. And, believe it or not, fresh Parmesan shavings are super easy to make. Starting with a wedge of Parmesan and using a vegetable peeler, in a downward motion, shave off thin strips from the wedge (one-half ounce makes about 2 tablespoons shavings). For the best flavor, seek out authentic Parmigiano-Reggiano cheese.
