Step 1: Prepare the Tortellini

1. Bring a large pot of salted water to a boil.
2. Add the cheese tortellini and cook according to the package instructions, about 5–7 minutes, until tender.
3. Drain the tortellini and set it aside.

Step 2: Sauté the Vegetables

1. Heat olive oil in a large skillet over medium heat.
2. Add the sliced onion, bell pepper, and mushrooms to the skillet.
3. Cook for 5–7 minutes, stirring occasionally, until the vegetables are tender and the onions are golden brown.
4. Remove the vegetables from the skillet and set them aside.

Step 3: Cook the Beef

1. In the same skillet, add the thinly sliced beef steak.
2. Season with salt and black pepper.
3. Cook over medium-high heat for 4–5 minutes, stirring occasionally, until the beef is browned and cooked through.

Step 4: Deglaze the Pan

1. Pour the beef broth into the skillet with the cooked beef.
2. Add Worcestershire sauce and stir to loosen any browned bits from the bottom of the pan.
3. Simmer for 2–3 minutes, allowing the sauce to reduce slightly.

Step 5: Combine Everything

1. Add the sautéed onions, bell peppers, and mushrooms back into the skillet with the beef.
2. Stir in the cooked tortellini, mixing well to ensure everything is evenly coated.

Step 6: Add the Cheese

1. Reduce the heat to low.
2. Sprinkle the shredded provolone cheese over the pasta mixture.
3. Gently stir until the cheese is fully melted and coats the pasta, beef, and vegetables.

Step 7: Serve

1. Serve the Philly Cheesesteak Tortellini Pasta hot.
2. Garnish with additional shredded cheese, fresh parsley, or red pepper flakes, if desired.
