Eggplant & Black Olive Calzones with Spicy Arrabiata Sauce

Once you get the hang of assembling calzones—oven-baked pizza turnovers—you’ll discover their endless versatility. They can be stuffed with any combination of veggies, meats, sauce, and cheese. Calzones are delicious right out the oven, but they also freeze well after baking. Let thaw at room temperature, then warm in a 350°F/180°C oven.
