Combine the garlic, ginger, soy sauce, wasabi (optional) and sesame in a bowl for the marinade. Place wahoo fillets in a shallow dish and pour marinade over the fish, allowing the fish to marinate for at least one hour. Grill fillets on direct heat until medium or medium well.
This recipe is also great for preparing fish tacos. Just place your fillets into corn tortillas and top with cilantro, Robért’s own homemade salsa and Cholula hot sauce (for the spice lovers).
