Preheat grill to sear setting, or an outdoor grill to med-high
Pour 1 tbsp lime juice over each filet
Evenly spread garlic on top and sprinkle with sea salt
Cover and place in the refrigerator for 5 minutes to allow juice to soak into the filets. (don't let them sit longer than this or they will begin to "cook" from the citric acid in the juice and you'll have ceviche instead.
Grill fish, skin side down, for 5 minutes,
Reduce grill heat to 375 degrees.
Flip and cook 6-7 minutes more until fish flakes with a fork.
Garnish with parsley and fresh lime.
