Cheesy polenta -- ready in 20 minutes -- is a satisfying side dish that easily pairs with whatever main dish is on the menu.
In a large saucepan, combine 4 cups water, 1 teaspoon salt, and 1 teaspoon pepper; bring to a boil. Whisking constantly, gradually add cornmeal. Reduce heat to medium-low; cook, whisking often, until thickened, 10 to 15 minutes.
Remove from heat, and stir in Pecorino and butter. Serve immediately, sprinkled with more pepper.
