Ingredients

  • 1 1/2 tablespoons olive oil
  • 1 1/2 tablespoons walnut oil
  • 1 1/2 tablespoons sherry vinegar
  • 1 large shallot, minced
  • Salt and freshly ground black pepper
  • 1/2 cup walnuts
  • 2 heads escarole, pale heart only, trimmed
  • 1/3 pound Gruyere, trimmed of any rind and cut into matchstick-size pieces
  • 1/2 cup minced Italian parsley

Method

  • To make the vinaigrette: In a small bowl, whisk together the oils, vinegar, shallot, and salt and pepper to taste.
  • Let stand 30 minutes to allow shallot flavor to mellow.
  • Taste and adjust the balance as needed.
  • Preheat the oven to 350F.
  • Toast the walnuts on a baking sheet until fragrant and lightly colored, about 15 minutes.
  • Let cool.
  • Break any large pieces up by hand.
  • In a large salad bowl, combine the escarole, walnuts, Gruyere, and parsley.
  • Add enough of the dressing to coat the salad lightly; you may not need it all.
  • Toss well.
  • Season with salt and pepper to taste and toss again.
  • Serve immediately.
