Spinach-Stuffed Pizza

Directions

1. 1
   Place thawed dough in a greased bowl, turning once to grease the top. Cover with plastic wrap and let rise in a warm place until doubled, about 1 hour.
2. 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 one 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. 3
   Sprinkle 1 cup mozzarella cheese onto bottom of crust. Top with spinach mixture; sprinkle with remaining mozzarella cheese.
4. 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 crust to seal. (Save remaining dough for another use).
5. 5
   Bake 25-30 minutes or until crust is lightly browned. 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.
