Heat oven to 375°F. Lightly grease 12-inch pizza pan. Unroll 1 can of dough; placing in greased pan. Starting at center, press out dough with hands to edge of pan. Layer pepperoni, mushrooms, olives and provolone cheese over dough.
Unroll remaining can of dough. Press out dough on work surface to form 12-inch round. Fold dough in half; place over provolone cheese and unfold. Press outside edges to seal. Cut several slits in top crust for steam to escape. Sprinkle with Parmesan cheese.
Bake 30 to 35 minutes or until crust is deep golden brown. Cut pizza into wedges; serve with warm pizza sauce.
