1. Cook the Pasta: In a large pot of boiling salted water, cook the pasta according to package instructions until al dente. Drain and set aside.
2. Sauté Vegetables: In a large skillet, heat olive oil over medium heat. Add the sliced onion and bell pepper, sautéing until softened (about 5 minutes). Add minced garlic and cook for another minute until fragrant.
3. Brown the Beef: Increase the heat to medium-high and add the thinly sliced beef. Season with salt and pepper. Cook until browned, about 5-7 minutes.
4. Add Flavorings: Stir in the Worcestershire sauce, beef broth, and heavy cream. Bring to a simmer and reduce the heat slightly. Allow to cook for 5 minutes.
5. Cheese Time: Gradually stir in the provolone cheese until melted and the sauce is smooth. If it seems too thick, add a little more beef broth.
6. Combine: Add the cooked pasta to the skillet, tossing to coat well with the creamy cheese sauce.
7. Taste and Adjust: Taste the pasta and adjust seasoning with additional salt and pepper if needed.
8. Garnish: Remove from heat, garnish with fresh parsley, and serve immediately.

By following these simple steps, you’ll create a dish that is not only easy to prepare but bursting with delicious flavors.
