First, fry sausage pieces in a small skillet until cooked through and browned, about 7-9 minutes. When done, set aside on a paper-towel lined plate.
If using store bought pizza dough, separate it into 4ounce servings, per person and allow to sit at room temperature for about 20 minutes. When ready, lightly flour a clean surface and use your fingertips to press into the dough, making it a circle.
Continue working on the dough, pressing it and stretching it with your fingertips. Then flour a rolling pin and roll out the dough, keeping it into a circle shape (best you can). You may have to flour under the pizza dough as well if it sticks and continue to roll out until it is about 9-10 inches in diameter.
Next, ladle tomato sauce onto the dough, leaving about a 1/4 inch border of no sauce. Then add your favorite toppings: dollops of ricotta cheese, shredded mozzarella, cooked Italian sauce, roasted peppers and grated Parmesan and pecorino. Drizzle the top with olive oil and place in a VERY hot 500 degree oven on a pizza stone (or you can pre-heat the bottom of a baking sheet and place pizza on that). Cook for 8-10 minutes until crust is golden browned and cheese has melted.
Once pizza is done, remove from oven and add additional toppings such as fresh oregano and basil and chili oil (optional, of course). Use a pizza cutter to cut pizza into 4-6 pieces and enjoy!
Of course toppings and topping measurements don't have to be exact..have fun with your pizza!
