Heat butter in 12 inch skillet over medium heat. Add the beef, pepper, onion and garlic, cooking until the beef is browned, about 7-10 minutes. Season with salt and pepper.
Add the pasta, broth, water and Worcestershire sauce. Bring to a boil and then reduce to simmer. Cover and cook for 15 minutes or until the pasta is cooked and the liquid has evaporated.
Stir in the cream cheese and half of the provolone. Top with the remaining provolone. Turn the oven to broil and broil for 2-3 minutes or until the cheese is melted.
Notes
If using ribeye, place it in the freezer for 45 minutes prior to slicing so you get thin slices.
If the pasta is soaking up the liquid too quickly, add broth 1 tablespoon at a time to reach desired consistency.
Cook the pasta until just al dente as it will cook more when broiling.
Don't use pre-shredded cheese. It contains wood pulp and preservatives so it doesn't melt well.
