1Whisk 1 tbsp olive oil, butter, onion, wine, Worcestershire sauce, lemon juice, parsley, seafood seasoning, garlic, and black pepper together in a bowl; add 1 tsp of Fairway Hot Chili Sauce for added kick, if desired; add shrimp. Toss to coat evenly. Cover bowl with plastic wrap and refrigerate for flavors to blend, at least 15 minutes.
2Lightly oil a heavy skillet, preferably of cast iron, and place over high heat until it is smoking hot. Coat steaks with 2 tsps Fairway olive oil; sprinkle steak with salt and pepper.
3Add steaks and cook until they are beginning to firm and have reached your desired doneness, about 5 to 7 minutes per side.
4Transfer steaks to a large serving plate and loosely tent with a piece of aluminum foil.
5Pour shrimp and marinade into skillet and cook until they are bright pink on the outside and the meat is no longer transparent in the center, 2 to 3 minutes per side. Optional: Serve with a side of Fairway Hot Chili Sauce for dipping.
