Grilled Swordfish with Niçoise Vinaigrette

From Gourmet Magazine

Ingredients:

5 tablespoons olive oil
Two 1-inch-thick swordfish steaks
1/4 cup finely chopped pitted Kalamata or other brine-cured black olives
1/4 cup finely chopped drained bottled roasted red pepper
3 tablespoons finely chopped fresh parsley leaves, preferably flat-leafed
1 tablespoon drained bottled capers, chopped fine
1 flat anchovy fillet, minced
1 small garlic clove, minced and mashed to a paste with 1/4 teaspoon salt
2 tablespoon minced scallion
1 1/2 tablespoons balsamic or red-wine vinegar
Lemon wedges as an accompaniment

 

Directions:

Prepare grill or heat cast iron grill pan over moderately high heat until it is hot. Brush each swordfish steak with 1 1/2 tablespoons olive oil and grill them, patted dry, for 4 to 5 minutes on each side, or until they are just cooked through. While the fish is cooking, in a small bowl stir together the olives, the roasted red pepper, the parsley, the capers, the anchovy, the garlic paste, the scallion, the vinegar, the remaining 3 1/2 tablespoons oil, and salt and pepper to taste. Transfer the swordfish to plates, spoon the sauce over it, and serve it with the lemon wedges.
