To create this remarkable dish of Surf and Turf, follow these straightforward steps:

1. Preheat Oven: Preheat your oven to 350°F (175°C).
2. Prepare Lobster Tails: Use kitchen shears to cut the top shell of the lobster tail, stopping just before the tail fins. Gently pull apart the shell to expose the meat.
3. Prepare the Steaks: Season the filet mignon steaks generously with salt and black pepper on both sides.
4. Sear the Steaks: Heat olive oil in a cast-iron skillet over medium-high heat. Sear the steaks for about 4-5 minutes on each side until browned but not fully cooked.
5. Add Garlic and Herbs: In the last minute of searing, add 2 tablespoons of butter, minced garlic, and half of the parsley to the pan. Baste the steaks with the melted butter for added flavor.
6. Transfer to Oven: Place the skillet in the preheated oven. Cook until steaks reach desired doneness, about 5-10 minutes depending on thickness.
7. Cook Lobster: In the meantime, boil or steam the lobster tails for about 8-10 minutes, or until the meat is opaque and cooked through.
8. Finish Sauce: Remove the skillet from the oven and let the steaks rest for 5-10 minutes. Meanwhile, melt the remaining butter with lemon juice and the rest of the parsley in a small saucepan over low heat.
9. Serve Together: On a plate, arrange the filet mignon alongside the lobster tail. Drizzle the garlic butter sauce over both.
10. Garnish: Optionally, garnish with fresh herbs for presentation.

This simple method ensures a delicious and visually impressive plate of Surf and Turf, capturing the essence of both ingredients.
