Preheat outdoor pizza oven to 800 degrees. If using an indoor oven, preheat to 450 degrees.
Prepare your pizza dough. While you can use most freshly made doughs about 10 minutes after making it, most store-bought pizza doughs must be out of the fridge for at least 30 minutes to warm up to room temperature. Check your specific instructions if you're using store-bought.
Some people roll out the dough with a rolling pin, and some like flattening it into a disc shape with their hands. I say you stick to what method you are most comfortable with. Use some flour to keep it from sticking to your hands, the counter, or your rolling pin.
Spread an even layer of flour and/or cornmeal on your pizza peel. Then place the flattened-out dough on the peel.
If you use a pizza pan/cookie sheet in the oven, most are non-stick, but adding a thin coat of olive oil which helps prevent any sticking and promotes even browning on the bottom of your pizza.
Take a spoon and apply the sauce one spoonful at a time.
Take the back of the spoon and spread it out over the dough, leaving about 1" of crust without sauce around the edge. Many people like using a "bullseye" pattern, swirling the sauce from the center out. Start with less sauce and add more as needed. It is easier to add more than take it away.
Once you're happy with your sauce distribution, add a thin layer of parma ham. Optionally, you can put the ham on top of the cheese.
Sprinkle your cheese of choice evenly over the top.
Launch the pizza into your pizza oven (or place your pizza into your oven).
In the pizza oven, turn a quarter turn every 1-2 minutes until cooked (about 4-8 minutes total).
In the inside oven, cook for 20-22 minutes, rotating the pizza halfway through cooking.
Check the bottom of the crust before pulling the pizza out of the oven.
Let the pizza rest for 5 minutes before slicing and then serve immediately.
