In a large soup kettle, cook the ground round, sausage, onions, red and green pepeprs, chili peppers, and garlic over medium-high heat, stirring often, until the meat is seared (but not browned), about 10 minutes. Pour off excess fat. Add the chili powder, salt, oregano, cumin, and bay leaves and stir for 1 minute. Add the tomatoes with their puree, breaking up the tomatoes with a spoon. Bring to a simmer. Reduce the heat to low and cook, stirring often, until the liquid is reduced, about 1- half hours. In a small bowl, combine the cornmeal and half cup of water. Stir the cornmeal mixture and the pink and black beans into the chili.Cook, stirring occasionally, until the chili is thickened, about 10 minutes. (The chli can be made up to 3 days ahead. If desired, scrape off and discard the solidified fat that rises to the surface. Reheat the chili gently on top of the stove before serving.) Makes about 25 servings.
