Polenta is made from coarsely ground cornmeal. It can be served with fish or chicken dishes or simply with a red sauce on top of it. You can also double this batch, pour it into a 9x13-inch pan, and then use it as an alternative gluten-free pizza crust. Simply top the polenta with pizza sauce, your favorite sautéed vegetables, and some organic grated cheese if you wish. Follow the directions for baking below.
