Cook the pasta according to package instructions until al dente. Drain and set aside.
In a large skillet, heat olive oil over medium-high heat. Add the sliced sirloin and season with salt and pepper. Cook for about 3-4 minutes, until browned, then remove from the skillet and set aside.
In the same skillet, add the sliced green bell pepper and onion. Sauté for about 5 minutes until the vegetables are tender. Add the minced garlic and cook for an additional minute.
Return the cooked steak to the skillet with the vegetables. Pour in the beef broth and Worcestershire sauce, simmering for about 2-3 minutes.
Lower the heat and add the softened cream cheese. Stir until the cream cheese has melted and created a creamy sauce.
Mix in the cooked pasta and half of the shredded provolone cheese, tossing until well combined. Adjust seasoning with salt and pepper to taste.
Transfer to a serving dish or bowl and top with the remaining provolone cheese.
Notes
Garnish with fresh parsley and serve hot for a beautiful finish. Consider adding a sprinkle of crushed red pepper flakes for a little heat!
