1. Preheat oven to 450°F. Coat a baking sheet with cooking spray.
2. Divide dough into 2 balls. On a lightly floured surface, spread each dough ball with your fingertips or the heel of your hand to make a 7- to 8-inch circle. Place half of the meatballs on each dough circle, forming a semicircle of filling on half of each dough circle and leaving a 1/2-inch border around the edge. Evenly distribute mushrooms, spaghetti sauce, and cheese over meatball halves. Fold dough over filling, forming half-moons. With your fingers or a fork, pinch edges together firmly to seal.
3. Place calzones on baking sheet and brush the top of each with 1 teaspoon oil. Pierce the tops 3 or 4 times with a fork or knife.
4. Bake 18 to 22 minutes, or until crust is golden. Serve with extra spaghetti sauce on the side.
