This grilled halibut with chimichurri represents a fresh and vibrant approach to seafood. The meaty, firm texture of the halibut provides the perfect canvas for the zesty, herb-forward sauce. Traditionally associated with grilled meats, this chimichurri uses flat-leaf parsley, lemon juice, and a hint of chilli to cut through the richness of the fish.
