Simple Grilled Swordfish is a great lean fish steak that is easy to make with ingredients you may already have on hand. Switch things up by using either lemon or lime juice.
In a shallow dish whisk together lime juice, vinegar, olive oil, salt, pepper, basil, and cayenne pepper in a bowl.
Put the swordfish in the bowl to cover and let marinate in the fridge for 15 minutes.
Preheat a grill to high heat (450-500 degrees). Grill the fish for 5-7 minutes per side, or until the fish flakes easily with a fork. Actual grilling time will depend on the thickness of your fillet.
