Deep dish pizza at home, hot from the oven, what could be better! I used a store-bought pizza crust to make this a little easier and made a quick delicious sauce. I used my cast iron skillet and prebaked the crust then filled it with Italian sausage, fresh spinach, mozzarella and fresh parmesan, just like my favorite pizzerias in Chicago! Bake until bubbly and hot, you'll be in heaven! You can also use a deep dish pizza pan or a springform pan.
