Cook the cheese tortellini according to the package instructions. Once cooked, drain and set aside.

In a large skillet, heat the olive oil over medium heat. Add the sliced onion and sauté until it becomes translucent.

Next, add the thinly sliced steak, cooking until browned. Season with a pinch of salt and pepper to taste.

Reduce the heat; pour in the heavy cream and add the provolone cheese. Stir until the cheese melts and the sauce becomes creamy.

Toss the cooked tortellini into the skillet, mixing everything until well combined. Adjust seasoning if needed.

Serve your Cheesesteak Tortellini hot, garnished with chopped parsley for a fresh touch.
