Ingredients

  • 1 1/2 tablespoons red-wine vinegar
  • 1 tablespoon Dijon-style mustard
  • 1/4 cup olive oil
  • 2 tablespoons finely chopped red onion
  • 1 tablespoon finely chopped fresh parsley leaves
  • 3/4 pound sirloin steak, about 1 inch thick
  • 1 garlic clove, halved
  • Boston lettuce, shredded, for lining the plates
  • 1 navel orange, peeled, the zest and pith cut away with a serrated knife and the sections cut away from the membranes

Method

  • In a bowl whisk together the vinegar, the mustard, and salt and pepper to taste, add the oil in a stream, whisking, and whisk the dressing until it is emulsified.
  • Stir in the onion and the parsley.
  • Rub the steak with the garlic, discard the garlic, and sprinkle the steak with salt and pepper to taste.
  • Broil the steak on the rack of a broiler pan under a preheated broiler about 4 inches from the heat for 4 to 5 minutes on each side for medium-rare meat and let it stand for 5 minutes.
  • Divide the lettuce between 2 plates, arrange decoratively on the top the steak, sliced thin diagonally, and the orange sections, and drizzle some of the dressing over each salad.
  • Serve the remaining dressing separately.
