In a saucepan, combine 2-3 tablespoons liquid for each 1 cup of polenta. The liquid can be milk (unsweetened oat or almond milk will work too), cream, broth, water or a mixture. Stir to break up the clumps, cover the pan and cook over low heat for 5 minutes, stirring once or twice. Add additional butter, cheese, salt and pepper to taste.
