In a bowl, whisk together olive oil, garlic and lime juice.
Add the fish to the bowl and turn once in the olive oil to coat and let sit for about 5 minutes.
Heat grill or grill pan to medium-high heat.
Remove the fish from the marinade and let excess drip off. Season with salt and pepper and grill about 6 minutes on each side until the flesh is opaque throughout.
With a fork, break the fish into large pieces and serve with tortillas and Mango or Corn Relish.
Notes
Gr8 Tips:
The tortillas can be warmed on the grill , directly on the gas burner or in a heavy skillet for a few seconds on each side until browned in spots. Keep them warm wrapped inside a clean kitchen towel.
