For first step in this recipe is to set up your outdoor grill, a hibachi or kettle grill with do just fine. Use natural hardwood charcoal. Start the fire with kindling and paper; light it with only matches-not lighter fluid. Lighter fluid will give the food an unnatural chemical taste. Get the charcoal to a medium heat and set the grill rack about 4 inches above the coals.
Make a few slits into the sides of the fish and insert the garlic slices into the incisions. Rub the fish with salt and oil. Grill for about 8 minutes per side. After turning the fish, rub olive oil and salt onto the spring onions and grill with the fish for the remaining 8 minutes. Remove fish and onions from the grill and onto a warm plate.
For the relish simply mix all of the ingredients together and scoop onto the hot fish (can be made a day inn advance).
