Cook the pasta according to the package instructions until al dente, then drain and set aside.

Heat olive oil in a large skillet over medium heat. Add the sliced Cajun sausage, chopped bell pepper, onion, and minced garlic. Cook until the sausage is browned and the veggies are tender.

Stir in the heavy cream and Cajun seasoning and bring to a gentle simmer.

Add the cooked pasta and cheese to the skillet, stirring until the cheese has melted and everything is well combined.

Season with salt and pepper to taste, mix well, and remove from heat.

Garnish with fresh parsley before serving hot.
