Instructions

  • Break the Italian sausage into small pieces.
  • Preheat the oven to 475°F (245°C).
  • Divide dough if making two pizzas, then roll very thin on a floured surface.
  • Transfer dough to a baking sheet dusted with cornmeal.
  • Spread a thin layer of sauce over the dough.
  • Add shredded mozzarella cheese evenly.
