Cook the pasta according to package directions and drain. In a large skillet, crumble and brown the ground beef.

Drain the meat and place it in a clean dish. In the same skillet, add the butter and let it melt. Then, add the mushrooms and cook until soft. After that, add the peppers and onions and sauté until they are soft too.

Reduce the heat and pour in the Worcestershire sauce. Then, add the can of French Onion Soup. Mix the cornstarch with a little water and add it to the skillet.

Whisk until the sauce thickens. Add the cooked ground beef back into the skillet and stir in the cooked and drained pasta.

Stir everything to combine well. Toss in the cubed provolone cheese and cover the skillet. Allow the cheese to melt. Season with salt and pepper if desired. Serve and enjoy!
