Creating Cheesesteak Tortellini in Creamy Provolone Sauce is straightforward when you follow these steps:

1. Cook the Tortellini: Begin by cooking the tortellini according to package instructions. Drain and set aside.
2. Sauté the Vegetables: In a large skillet, heat the olive oil over medium heat. Add the diced bell peppers and onions, cooking until they soften (about 5 minutes).
3. Cook the Beef: Increase the heat to medium-high. Add the thinly sliced beef to the skillet and season with salt, pepper, and Italian seasoning. Cook until the beef is browned and cooked through (about 3-5 minutes).
4. Add Garlic: Stir in the minced garlic and cook for an additional 1-2 minutes until fragrant.
5. Prepare the Sauce: Pour in the heavy cream, stirring well to combine. Allow the mixture to simmer for about 3-4 minutes, letting the sauce thicken slightly.
6. Incorporate Cheese: Gradually add the shredded provolone cheese, stirring until melted and the sauce is creamy.
7. Combine: Gently fold in the cooked tortellini until well-coated with the sauce.
8. Taste and Adjust: Taste the dish and adjust seasoning as necessary with additional salt and pepper.
9. Garnish and Serve: Remove from heat, garnish with fresh parsley, and serve warm.
