In a medium bowl stir together fontina cheese, Parmesan cheese, and basil. Set aside.
For polenta, in a medium saucepan bring 2-3/4 cups water to boiling. Meanwhile, in a bowl stir together cornmeal, the 1 cup cold water, and salt. Slowly add cornmeal mixture to boiling water, stirring constantly. Cook and stir until mixture returns to boiling. Reduce heat to very low. Cook for 10 to 15 minutes or until mixture is very thick, stirring occasionally .
Pour one-third of the hot mixture to a greased 2-quart square baking dish. Sprinkle with half of the cheese mixture. Repeat layers, ending with the hot mixture. Cool for 1 hour. Cover with foil and chill several hours or overnight until firm.
Bake polenta, uncovered, in a 350 degrees F oven about 40 minutes or until lightly browned and heated through. Let stand for 10 minutes before serving. Serve with Tomato-Basil Sauce. If desired, garnish with additional basil.
