Quick creamy polenta

Method

1. Pour 800ml of water into a large saucepan and bring to the boil, then pour in the polenta in a steady stream. Stir constantly over a medium heat until it comes back to the boil, then turn down the heat to very low and simmer for 1 minute.
2. Remove from the heat, season with salt and pepper, then stir in the cheese and butter. Spoon into a serving dish, sprinkle with extra cheese and serve with the stir-fry.
