Ingredients

2 tablespoons fresh lemon juice

1 tablespoon coarsely chopped fresh flat-leaf parsley

1/4 teaspoon Dijon mustard

Pinch of sugar

Coarse salt and freshly ground pepper

1/4 cup plus 2 tablespoons extra-virgin olive oil

1 small head frisee, torn into small pieces (about 2 cups)

2 cups baby spinach (about 1 1/2 ounces)

2 radishes, trimmed and very thinly sliced

2 scallions (green parts only), cut on a bias into 1/2-inch-thick pieces

Preparation

Whisk together lemon juice, parsley, mustard, and sugar in a large bowl; season with salt and pepper. Add oil in a slow, steady stream, whisking until emulsified; set aside.

Toss together frisee, spinach, radishes, and scallions on a large platter. Just before serving, drizzle with some of the dressing. Serve remaining dressing on the side.
