Hot breakfast cereal. Dice polenta and heat with milk, stirring until creamy; add cinnamon, brown sugar, and fresh fruit or dried cranberries.
Mini-pizzas. Broil polenta slices, remove from the oven, and spread with tomato sauce. Sprinkle with diced cooked meat or sautèed veggies (or both!); top with cheese. Pop back in the oven until the cheese melts.
Lasagna. Spread pasta sauce in an oven-safe baking dish. Slice polenta into 1/4-inch rounds and layer with ricotta cheese, cooked ground beef or turkey, and shredded cheese. Add another layer of polenta slices; top with sauce and cheese. Bake in a 350-degree oven for about 45 minutes, or until lightly browned on top.
