Preheat the oven to 400 degrees F.
Stretch the crust over a 14-inch pizza pan. Evenly spread the sauce over the crust. Arrange the steak and red onions over the sauce. Mix the mozzarella and provolone cheeses together in a bowl then distribute them evenly over the pizza. Season with dried oregano, if desired. Bake the pizza until the crust is crisp and brown, about 10 to 15 minutes. Remove the pizza from the oven, cut it into wedges, and serve.
