SPINACH STUFFED PIZZA
1 loaf (1 lb) frozen bread dough, thawed
1 package (10 oz) frozen chopped spinach, thawed and squeezed dry
1 cup chopped fresh mushrooms
½ cup chopped onion
¼ tsp salt
1/8 tsp pepper
2 cups shredded mozzarella cheese
½ cup pizza sauce
2 tbsp shredded Parmesan cheese
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.
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. spring form pan coated with cooking spray; press dough onto bottom and partway up sides of pan.
Sprinkle 1 cup mozzarella cheese onto crust. Top with spinach mixture; sprinkle with remaining mozzarella cheese.
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.)
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.
