Rub the fillets with vegetable oil and season with salt and pepper to taste.
Grill the fillets skin-side up over a medium-hot
fire for 3 to 4 minutes. Flip them and cook an additional 2 to 3
minutes, until the fish is opaque all the way through.
Remove the fillets from the fire, drizzle them with
the olive oil, squeeze a half lime over each, and sprinkle them with the
parsley.
