How to Make It
Step 1
Light a grill. Rub the skinless side of the fillets with 1 tablespoon of olive oil. Sprinkle with the rosemary and season with salt and pepper. Sandwich the fillets together to re-form the fish. Rub the skin with another tablespoon of olive oil and season with salt and pepper. Loosely tie the fillets together with cotton string.
Step 2
Generously oil the grill. Grill the fish over a moderately low fire until just cooked through and the skin is browned and crisp, about 10 minutes per side. Transfer the fish to a platter and remove the strings. Cut the fish into 4 pieces and serve at once.
