Cook the penne pasta according to package instructions until al dente. Drain and set aside.
In a large skillet, heat the olive oil over medium-high heat. Add the sliced sirloin steak and cook for about 3-4 minutes until browned. Remove the steak from the skillet and set aside.
In the same skillet, add the onion and green bell pepper. Sauté for about 5 minutes until softened. Add the minced garlic and cook for an additional 1 minute.
Return the cooked steak to the skillet. Pour in the beef broth, heavy cream, Worcestershire sauce, salt, and black pepper. Stir to combine and bring to a simmer.
Reduce the heat to low and stir in the provolone cheese and Parmesan cheese until melted and creamy.
Add the cooked penne pasta to the skillet and toss to coat in the sauce.
Serve immediately, garnished with extra cheese if desired.
