Brown the Sausage: In a large skillet, cook the Italian sausage over medium heat until it's nicely browned and fully cooked, about 6-8 minutes.

Sauté the Veggies: Add the chopped onion, bell peppers, and minced garlic to the skillet. Sauté until tender, around 5 minutes.

Incorporate the Cream: Pour in the heavy cream and Italian seasoning. Stir gently until mixed and thickened slightly, about 2-3 minutes.

Season to Taste: Sprinkle in salt and pepper according to preference. Taste to ensure it’s to your liking.

Mix in Pasta and Cheese: Add the cooked pasta and grated Parmesan cheese. Stir until evenly coated, about 2 minutes.

Simmer Together: Let everything simmer for about 5 minutes, ensuring it's heated through and flavors meld.
