Slighty grease pizza pan, and spread dough.
Then cover really good in sauce.
Be generous, if not you will have a dry pizza.
Then add your hamburger meat over the pizza, then spread the onion and peppers, ham, and rest of the ingedients, then top with the pepperoni and then the cheese.
Bake in a preheated 450º oven, till it is finished.
About 10 minutes or till cheese is slightly browned.
