Cook the Tortellini: Boil the tortellini according to package instructions. Drain and set aside.
Cook the Steak: Heat olive oil in a large skillet over medium-high heat. Add the sliced beef and cook for 2–3 minutes per side, until browned and cooked through. Remove from the skillet and set aside.
Sauté Vegetables: In the same skillet, add the bell pepper, onion, and garlic. Cook for 3–4 minutes, or until the vegetables are softened.
Make the Sauce: Reduce the heat to medium. Pour in the heavy cream and bring it to a gentle simmer. Stir in the provolone and Parmesan cheese until melted and smooth. Season with salt and pepper.
Combine: Add the cooked tortellini and steak back into the skillet. Toss to coat everything in the creamy sauce.
Serve: Garnish with chopped parsley if desired and serve immediately.
