Pre-heat your oven at 425ºF (220ºC).

Grease a 14 inch (35 cm) pizza pan with the olive oil.

Place the pizza dough on a flat, floured surface and press down the edges to make your crust. You can make it as thick or as thin as you want. Press the center of the dough with your fingers and start stretching it to make a small disc. Place your hands under the dough, lift it and start stretching it with your knuckles, let the weight of the dough help you stretch it. Keep stretching until the dough is the size of your pan. If you see any small holes, you can pinch them closed with your fingers.

Now, place the stretched dough on the greased pizza pan and add your pizza sauce. Place the meatballs, green peppers and mushrooms over half of the pizza since we won't be putting any toppings on the other half. Now, add the mozzarella cheese on the entire pizza and bake for 12-18 minutes or until the cheese has melted and the edges are golden brown.
