On a lightly floured surface, roll out pizza dough into a large rectangle about 14x10 inches.
In a large bowl, combine ham, sausage, mozzarella, ricotta, Parmesan, basil, oregano, parsley, garlic powder, red pepper flakes, salt, and pepper. Mix until well blended.
Spread the cheese mixture onto the dough, leaving a 1-inch border. Roll up the dough from the long side, forming a cylinder. Place on a sheet pan lined with parchment paper.
Brush the top of the stromboli with olive oil. Bake for 25-30 minutes, or until golden brown.
Let cool for 10 minutes before slicing and serving.
