Preheat your oven to 450 degrees. In a spring form, brush the sides and bottom with olive oil and spread 3/4 of the dough on the bottom and up the sides. Add a layer of sliced mozzarella to the dough. In a large bowl mix together the spinach and ricotta. Then place this mixture into spring form pan and liberally add fresh pepper.

Top the spinach mixture with mozzarella cheese and then roll the other 1/4 of the dough into a large circle and top the pizza. Pinch all the sides together and place into the oven for 10 minutes.After being in the oven for 10 minutes remove the pizza and spoon the 2 cups of tomato sauce onto the pizza. Place back into the oven and release the spring form pan to let the sides bake. Let it bake for about 10 minutes more and then remove your pizza. You are ready to go!
