Spinach-Stuffed Pizza

Directions

1. Place thawed dough in a greased bowl, turning once to grease the top. Cover with plastic and let rise in a warm place until doubled, about 1 hour.
2. Preheat oven to 400°. In a large bowl, mix spinach, mushrooms, onion, salt and pepper. Punch down dough; divide into thirds. On a lightly floured surface, roll 1 portion of dough to a 10-in. circle. Transfer to a 9-in. springform pan coated with cooking spray; press dough onto bottom and partway up sides of pan.
3. Sprinkle 1 cup mozzarella cheese onto crust. Top with spinach mixture; sprinkle with remaining mozzarella cheese.
4. On a lightly floured surface, roll out a second portion of dough to a 10-in. circle; place over cheese layer. Pinch together top and bottom crusts to seal. (Save remaining dough for another use.)
5. Bake until crust is lightly browned, 25-30 minutes. Spread pizza sauce over top; sprinkle with Parmesan cheese. Bake 5-6 minutes longer or until cheese is melted. Let stand 5 minutes before cutting.
