1. Arrange a rack in middle of oven and preheat to its hottest setting, 500°F-550°F.
2. Lightly oil a cast iron pan and dust lightly with cornmeal, if desired. Or, lightly oil and dust a baking sheet. Shape dough into a circle, pushing gently until fairly thin.
3. Spread on the sauce almost to the edges of the flatbread and sprinkle on the garlic.
4. Top generously with the shredded mozzarella, oregano and all the meats.
5. Grate on parmesan to taste then place in the oven to bake for 12-15 mins, or until the crust is puffy, crisp and slightly blistered. Top with fresh basil leaves and enjoy immediately with red pepper flakes.
