Shrimp and Grits With Kielbasa

2 cups dry polenta

5 cups water

1 tablespoon salt

2 tablespoons olive oil

1 kielbasa sausage, chopped

3 tablespoons minced garlic

2 tablespoons chopped fresh rosemary

2 tablespoons red pepper flakes

1 pound uncooked shrimp - peeled, deveined, and tails removed

8 ounces shredded sharp Cheddar cheese

Bring polenta, water, and salt to a boil in a saucepan; reduce heat to low and simmer until polenta is thickened, 10 to 15 minutes.

Heat olive oil in a large skillet over medium heat and cook kielbasa sausage until browned, 5 to 8 minutes; stir in garlic, rosemary, and red pepper flakes and cook, stirring often, until garlic is fragrant, about 1 minute. Mix in shrimp and stir gently until shrimp are pink and no longer translucent inside, about 5 minutes.

Transfer shrimp mixture and any pan juices to a large serving bowl and stir grits into the mixture. Stir Cheddar cheese into the hot mixture until melted.
