Cook cheese tortellini according to package instructions; drain and set aside.
In a large skillet, heat olive oil over medium heat. Add sliced onions and sauté until softened, about 5-7 minutes.
Incorporate cubed beef into the skillet; season with salt and pepper. Cook until browned on all sides (6-8 minutes).
Pour in beef broth and Worcestershire sauce; stir and let simmer for 3-4 minutes.
Reduce heat to low and sprinkle shredded provolone over the mixture; stir until melted.
Gently fold in cooked tortellini, ensuring they are well coated with the sauce.
