Delicious served with a side of Braised Broccoli Rabe.
Place fish fillets in a shallow dish. Mix lemon juice, olive oil, garlic, oregano or mint, salt, and black pepper. Pour over fish and refrigerate for one hour. Preheat a grill or sauté pan to medium high heat. Grill or sauté swordfish for about 5 minutes on each side depending on thickness and desired degree of doneness. Meanwhile, heat marinade in a small saucepan, or in the skillet used to cook the swordfish, until boiling for 1 minute. Serve hot marinade over grilled fish with a pinch of fresh mint for garnish
