Broiled Caribbean Mahi Mahi

This recipe was inspired by the grilled wahoo we learned to make in Barbados. To simplify prep, we narrowed the long list of herbs and aromatics used to season the fish to just scallions and fresh thyme. And instead of a pre-grill marinade, we keep the flavors clean and bright by finishing the fish with a vibrant sauce. Mahi mahi is a widely available stand-in for hard-to-find wahoo; you also can use grouper or snapper fillets. Rice and beans are excellent accompaniments.
