Balsamic Mushroom and Onion Calzone

There is just something so satisfying about breaking into a sauce-smoothered dough to have cheese and delicious ingredients spill out! I had some extra pizza dough on hand recently and I rummaged though my brain (and fridge!) to see what I could fill it with...the result was a super yummy calzone that had my family wishing I had more leftover dough :)

Serves 6
----------
-1 lb pizza dough, split into 6 equal parts
-2 tablespoons olive oil
-1 large vidalia onion, sliced into strips
-1 lb fresh crimini mushrooms, sliced
-3 tablespoons balsamic vinegar
-2 tablespoons fresh tarragon or 1 tablespoon dried tarragon
-salt and pepper to taste
-2 cups shredded cheese (I recommend an Italian blend of mozzarella and parmesan)

Sauce
-------
-1 tablespoon olive oil
-4 large tomatoes
-3 cloves of garlic
-2 tablespoons dried Italian seasoning
-1/2 cup water
-salt and pepper to taste

To make
----------
-Pre-heat oven to 375 degrees Fahrenheit
-Spray a baking sheet with non-stick cooking spray
-On a clean surface sprinkled with flour, roll out each mound of dough to about 8-10 inches x 4 inches
-Heat olive oil in a skillet and cook onions for about 5 minutes until halfway cooked. Add mushrooms, balsamic vinegar, salt and pepper and continue cooking on medium heat about 5-10 more minutes, until the onions have caramelized and the vinegar has reduced to a glaze. Stir in the tarragon and remove from heat.
-Place about 1/2 cup to 2/3 cup onion and mushroom mixture on on side of dough. Sprinkle 1/3 cup cheese on top of onion mixture. Fold over the long end of the dough and crimp the edges closed. Repeat with remaining dough and mixture.
-Arrange calzones on baking sheet and bake for about 12-17 minutes, or until the top is golden and the dough seems cooked. Cooking time will vary depending on your dough.
-While the calzones are baking, prepare the sauce by heating oil in a sauce pan. Puree tomatoes and garlic and add to the heated oil. Add seasoning, water, salt and pepper and cook on medium heat until the sauce has thickened and reduced to desired consistency, about 10 minutes.
-Remove Calzones from oven and put onto individual serving plates. Spoon about 1/2 cup sauce on to each calzone and serve.
-Enjoy!
