We suggest setting out a basket of thinly sliced rustic bread, so guests can make sandwiches if they like. Ingredients 2 flank steaks (3 ½ to 4 pounds total) 2 tablespoons plus ⅔ cup extra-virgin olive oil, divided Coarse salt and freshly ground pepper 6 ounces mixed pitted brine-cured olives, chopped (1 ½ cups) ½ cup chopped peperoncini, plus ⅓ cup reserved juice ⅔ cup chopped fresh flat-leaf parsley leaves, plus 3 tablespoons finely chopped parsley stems (from 1 small bunch) Directions Let steaks sit at room temperature 1 hour. Heat grill to medium-high. Pat steaks dry. Brush with 2 tablespoons oil, and season liberally with salt and pepper. Grill 7 to 8 minutes per side (or until internal temperature reaches 135 degrees) for medium-rare. Let steaks rest, loosely tented with foil, 10 minutes. Meanwhile, mix together olives, peperoncini and their juice, parsley leaves and stems, oregano, and remaining 2/3 cup oil. Sauce can be made 1 day in advance and refrigerated; bring to room temperature before serving. Thinly slice steaks against the grain; arrange on a platter. Spoon half the sauce on top; serve remaining sauce on the side. Rate it Print
