Creating this luxurious dish is straightforward if you follow these steps:

1. Prep the Ingredients: Ensure all ingredients are measured and prepared before starting to cook.
2. Cook the Steak: In a large skillet, heat 2 tablespoons of olive oil over medium-high heat. Season the flank steak with salt and pepper. Sear for about 3-4 minutes per side until browned and cooked to your liking. Remove and let rest.
3. Sauté the Shrimp: In the same skillet, add the remaining olive oil and 2 tablespoons of butter. Once heated, add minced garlic and crushed red pepper flakes. Sauté for 1 minute.
4. Add Shrimp: Place the shrimp in the skillet and cook for about 2-3 minutes on each side until they turn pink and opaque.
5. Deglaze the Pan: Pour in the white wine, scraping the bottom of the pan to release any flavorful bits. Simmer for 2-3 minutes until slightly reduced.
6. Finish the Sauce: Add the lemon juice and remaining butter to the skillet, stirring until melted and combined.
7. Slice the Steak: While the shrimp are cooking, slice the rested steak against the grain into thin strips.
8. Combine: Add the sliced flank steak back into the skillet with the shrimp. Toss gently to coat everything in the sauce.
9. Garnish: Remove from heat and sprinkle with fresh parsley.
10. Serve: Arrange the dish on a large platter or individual plates and serve with pasta or crusty bread.
