Ingredients

  • 12 ounces broccoli, rinsed and cut into 1-inch pieces
  • 1 1/2 teaspoons olive oil
  • About 1/8 teaspoon salt
  • 1 1/2 tablespoons balsamic vinegar
  • 1/2 teaspoon Dijon mustard
  • 1/3 cup chopped toasted walnuts
  • 1/2 cup frisee leaves (optional), rinsed and crisped
  • Pepper

Method

  • In a 10- by 15-inch baking pan, mix broccoli, oil, and 1/8 teaspoon salt. Spread in a single layer.
  • Bake in a 450° oven, stirring occasionally with a wide spatula, until broccoli is browned and tender when pierced, 20 to 25 minutes.
  • Meanwhile, in a bowl, mix balsamic vinegar and mustard. Add warm broccoli, walnuts, and frisee, if using, and mix to coat. Add salt and pepper to taste.
