Preheat broiler. Place Swordfish on non-stick surface, sprinkle lightly with garlic powder and black pepper, add several drops of Balsamic Vinegar. Broil on High for 6-7 minutes, then turn over fish, sprinkle on a few more droplets of Balsamic Vinegar and broil for approximately 5-6 more minutes (depending on the thickness of the cut). Use a spatula to move fish to plate. It will be moist and delicious – without any need for added oil, butter or salt. Try serving it with fresh grape tomatoes (sliced into halves, sprinkled with fresh black pepper). Add a slice or two of lemon as a garnish.
