Bring a large pot of salted water to a boil. Add pasta and cook according to package instructions until al dente, about 8-10 minutes. Drain and reserve a bit of pasta water.

In a large skillet, heat olive oil over medium heat. Sauté sliced onions and bell peppers until tender, about 5 minutes.

Add sliced beef to the skillet and cook for 5-7 minutes until browned and cooked through.

Stir in minced garlic and reserved pasta, then add provolone cheese, mixing until melted.

Season with salt and pepper to taste. Serve immediately and enjoy!
