Let’s dive into creating this delightful dish. Remember, cooking is as much about enjoying the process as it is about the end result.

1. Begin by cooking the shell pasta according to package instructions. Drain and set aside.
2. In a large skillet, heat olive oil over medium-high heat. Add the steak bites, seasoning them with salt and pepper, and cook until browned and cooked to your liking, about 3-4 minutes per side. Remove from the skillet and set aside.
3. In the same skillet, reduce the heat to medium and add the butter. Once melted, add the minced garlic and sauté for about 1-2 minutes until fragrant, being careful not to let it burn.
4. Add the cooked pasta to the skillet, tossing it in the garlic butter sauce until well coated. Stir in the Parmesan cheese, allowing it to melt into the sauce.
5. Return the steak bites to the skillet, along with any juices. Toss everything together, ensuring the steak and pasta are well combined and heated through.
6. Garnish with fresh parsley and, if desired, a squeeze of lemon juice and a sprinkle of red pepper flakes for a bit of zest and heat.
