Start by boiling a large pot of salted water. Once the water is at a rolling boil, add the tortellini. Cook according to the package instructions until al dente, usually around 5-7 minutes. Drain and set aside.

In a large skillet, heat the olive oil over medium heat. Add the sliced onions and bell peppers. Sauté them for about 5-7 minutes until they’re tender and caramelized. Toss in the minced garlic and stir for an additional minute.

Push the vegetables to the side of the skillet and add the thinly sliced beef to the pan. Cook for about 3-5 minutes, stirring occasionally, until the beef is browned and cooked through.

Add the drained tortellini into the skillet with the beef and vegetables. Stir to combine, ensuring that all ingredients are mingling together.

Sprinkle the provolone cheese over the top of the mixture. Cover the skillet with a lid and allow it to cook for a few minutes until the cheese has melted.

Season the dish with salt and pepper to taste. Once everything is fully combined, serve hot and enjoy!
