In a large pot of salted boiling water, cook the pasta according to package instructions until al dente. Drain and set aside.
In a large skillet, heat the olive oil over medium heat. Add the sliced onion and bell peppers, and sauté for about 5 minutes until they are softened and slightly caramelized. Stir in the minced garlic and cook for another minute until fragrant. Remove the vegetables from the skillet and set aside.
In the same skillet, increase the heat to high and add the thinly sliced beef. Season with salt and pepper, and cook for 3-4 minutes until browned, stirring frequently.
Pour in the beef broth and Worcestershire sauce, scraping the bottom of the skillet to lift any flavorful bits. Bring to a simmer, then reduce the heat to medium-low and stir in the heavy cream.
Slowly add the provolone cheese, stirring continuously until melted and the sauce is creamy.
Add the cooked pasta and sautéed vegetables back into the skillet, stirring everything together until well combined. Cook for an additional 2-3 minutes to heat through.
Taste and adjust seasoning if needed, adding more salt and pepper to your preference.
