Pour vegetable oil in the cold Dutch Oven, spreading it around the bottom and sides of the Dutch Oven.
Take the pizza dough out of the tube and split it in half. Spread half of the dough in the bottom of the Dutch Oven.
Spread the tomato sauce over the pizza dough and sprinkle with garlic powder, salt, and pepper to taste. Add sliced onions and sliced pepperoni. Add additional pizza toppings at this time.
Place the dutch oven on the prepared hot coals.
After the pizza has cooked approximately 10 minutes and the dough is baked, remove the lid and sprinkle with mozzarella and cheddar cheese.
Place lid back on the Dutch Oven and let the cheese melt. The more hot coals placed on the lid, the faster the cheese will melt.
When cheese is melted, remove lid and then remove the Dutch Oven from the coals. You’re pizza is now ready to eat.
