- Preheat the oven to 350°F. 
- In a large skillet, heat olive oil over medium heat. Add the diced onion, green bell pepper, and mushrooms. Sauté for about 5 minutes until the vegetables are softened. 
- Add minced garlic and cook for an additional minute. 
- Add the ground beef to the skillet, breaking it apart with a spoon. Cook until browned, about 5-7 minutes. Drain excess fat if necessary. 
- Stir in salt, black pepper, Italian seasoning, Worcestershire sauce, and beef broth. Bring to a simmer. 
- In a large mixing bowl, combine the cooked pasta with the beef mixture. Stir in half of the provolone and mozzarella cheese. 
- Transfer the mixture to a greased 9x13-inch baking dish. Top with the remaining cheese. 
- Bake in the preheated oven for 20-25 minutes, or until the cheese is bubbly and golden. 
- Let it cool for 5 minutes before serving.
