Make the pizza sauce (see link in post).
Preheat oven to 475° and place rack on highest level that will eventually fit cast iron pan.
Heat 1 tsp. of olive oil in a pan. Add the mushrooms and wine. Saute the mushrooms for 6 - 7 minutes, stirring occasionally, until mushrooms soften. Remove from heat and set aside.
Spread some flour on a cutting board, Combine remaining oil with dough and stretch room temperature dough to the diameter of your cooking pan (cast iron preferred for this recipe).
Heat a cast iron pan to medium heat (if using for pizza, otherwise use a separate pan and combine later). Brown the sausage, stirring occasionally for 5 - 6 minutes. Set aside leaving rendered fat in pan.
Remove the cast iron pan from heat. Add stretched dough to pan and form to fit, using a wooden spoon to help form the high sides of the eventual crust and smoothing out the dough.
Set over medium heat (from the sausage burner) for 3 - 5 minutes as this will help the crust set better. While heating layer in the pizza sauce, sausage, mushrooms, crushed red pepper, and sliced red onion. Top with mozzarella.
Carefully place in oven. Cook for 12 - 15 minutes or until upper crust starts to brown and cheese is bubbling.
Carefully remove from oven and let cool for 5 - 10 minutes. Top with fresh parmesan and fresh herbs (basil or oregano, preferred). Cut into desired portions and serve.
