Preheat oven to 450°F. Roll out dough or press into an oiled pan creating a slight rolled edge. Pre-bake crust for 5-6 minutes until set but not browned.
Using your hands, crush the tomatoes between your fingers as you place them on the crust. Sprinkle with oregano and salt. Sprinkle with half the Romano.
Mix the mozzarella and smoked cheddar together and sprinkle on a little less than half.
Add the browned sausage, using your hands to break into smaller pieces, if desired. Then add the cooked prosciutto and peperoncinis.
Add the final layer of the mozzarella and cheddar on top of everything. Finish with Romano and a drizzle of olive oil. Bake for 12-15 minutes of the middle rack until crust is browned and cheese is bubbly.
