Once known as "poor man's lobster," monkfish takes wonderfully to the grill. It holds up to the heat without falling apart yet remains tender and flavorful.
Juice the limes, and process the juice along with the olive oil, jalapeño, and garlic in a food processor. Add a little salt and pepper, if desired as well.
Pour this mixture over the fish and let marinate at room temperature for 20 minutes, or cover and refrigerate for 1 hour.
Meanwhile, soak the skewers, if you're using wooden ones. Preheat the grill to medium. Monkfish is best when thoroughly cooked, so we want a temperature that will cook the inside without drying the outside.
Place the monkfish cubes on the skewers. Sprinkle with salt and pepper, if desired. Grill for about 3 to 4 minutes on each of the cube's 4 sides. When cooked through, the monkfish will be browned and tender.
