For a mouthwatering seafood dish, try marinating tuna steaks in soy sauce. The soy sauce infuses the tuna with a savory flavor and helps to tenderize the meat. Grill or sear the marinated tuna steaks for a few minutes on each side until they are cooked to your desired level of doneness. Serve with a side of roasted potatoes and a fresh salad for a satisfying meal.
