In a large pot of salted boiling water, cook the cheese tortellini according to the package instructions until al dente. Drain and set aside.
In a large skillet, heat 1 tablespoon of olive oil over medium-high heat. Add the thinly sliced ribeye steak, seasoned with salt and pepper. Cook for about 3-4 minutes until browned, then remove from the skillet and set aside.
In the same skillet, add another tablespoon of olive oil. Add the sliced onion and bell pepper, sautéing for about 5-6 minutes until they are softened. Stir in the minced garlic and cook for an additional 1 minute until fragrant.
Return the steak to the skillet, and pour in the beef broth. Bring the mixture to a simmer and let it cook for 2-3 minutes to blend the flavors.
Gently fold in the cooked tortellini and stir until well combined.
Lower the heat and sprinkle the shredded provolone cheese over the tortellini mixture. Stir continuously for about 2-3 minutes until the cheese is melted and the sauce is creamy. If the sauce is too thick, add a little more beef broth to reach your desired consistency.
Taste and adjust seasoning with extra salt or pepper if needed. Serve hot, garnished with chopped fresh parsley.
Notes
Adjust the thickness of the sauce with additional beef broth if necessary.
