Ingredients

  • 1 3/4 lb collard greens
  • 7 large brine-cured green olives (2 1/4 ounces), pitted
  • 2 garlic cloves, chopped
  • 1/3 cup water
  • 1/2 teaspoon balsamic vinegar
  • Scant 1/2 teaspoon salt
  • 1/4 teaspoon cayenne
  • 1/4 teaspoon black pepper
  • 1/2 cup extra-virgin olive oil
  • 1 oz finely grated Parmigiano-Reggiano (1/2 cup)

Method

  • Bring a 6- to 8-quart pot of salted water to a boil.
  • Meanwhile, cut stems and center ribs from collard greens and discard.
  • Stir collards into water in batches, then simmer, uncovered, stirring occasionally, until tender, about 15 minutes.
  • Transfer collards with tongs to a colander to drain, gently pressing on greens to extract excess water.
  • (If making pasta, reserve water in pot for cooking pasta.)
  • Coarsely chop collards.
  • Blend olives and garlic in a food processor until finely chopped.
  • Add collards, water, vinegar, salt, cayenne, and pepper and pulse until finely chopped.
  • With motor running, add oil in a slow stream.
  • Turn off motor, then add cheese and pulse to combine.
