Bring a large pot of salted water to a boil.

In a skillet, heat the olive oil over medium heat and add the sliced onion and bell pepper. Sauté for about 5 minutes until they are tender.

Add the thinly sliced beef to the skillet with the vegetables. Cook until the beef is browned.

Sprinkle the garlic powder, salt, and pepper over the beef and veggies. Stir to combine.

Pour in the beef broth and bring to a simmer.

Stir in the heavy cream and mix well.

Drain the pasta and add it directly into the skillet, tossing to combine.

Sprinkle the provolone cheese over the pasta and stir until it's melted.
