I tried this today!
I made a half recipe in a round pizza pan. I baked the "crust" at 450 for 10 minutes, removed it from the oven, transferred it to a sheet pan, blotted the fat and moisture from the top with paper towels. I topped it with tomato sauce, Romano cheese, mozzarella cheese, red onion rings, and black olives. I baked it for an additional 12 minutes at 450 and then let it rest for about 10 minutes before serving. The edges were crispy, the cheese was brown, it had all of the flavor elements of a pizza.
I'm thinking that this might make a nice breakfast pizza. The shell made with breakfast sausage, topped with beaten eggs, a splash of heavy cream, cayenne pepper, grated cheese and some chopped broccoli or chopped spinach.
