Preheat oven to 450˚F. Spread polenta crust with 1/2 cup strained tomatoes or pizza sauce. Top with desired ingredients such as grated cheese, olives, mushrooms, peppers, artichokes, basil and meats, such as prosciutto, pepperoni or sausage. Bake for 12-15 minutes, until the polenta is hot and a little crispy on the bottom. Cool for a few minutes, cut into 8 wedges, and serve.
