Ingredients

2 teaspoons unsalted butter

18 pearl onions, peeled

4 ribs celery, cut into 1/4-inch-thick slices

18 button mushrooms

3 small turnips, peeled, or 12 baby turnips

18 baby carrots, scraped, or 3 large carrots, peeled and cut into 1/4-inch slices

1 bunch radishes, greens trimmed to 1/4 inch

3 boneless, skinless chicken breasts (about 1 pound)

2 cups Homemade Chicken Stock or low-sodium canned, skimmed of fat

1 head romaine lettuce, outer leaves discarded

3 tablespoons white-wine vinegar

3 tablespoons Dijon mustard

2 tablespoons honey

3 tablespoons extra-virgin olive oil

1 teaspoon salt

1/4 teaspoon freshly ground pepper

Preparation

Heat butter in a soup pot over medium heat. Add onions, celery, and mushrooms; toss to coat. Add turnips, carrots, and radishes; stir to combine. Add chicken, stock, and 4 cups water, or enough to cover. Bring to a boil; reduce to a simmer. Cook until vegetables are just tender and chicken is cooked through, about 15 minutes.

Fill a large bowl with water and ice; set aside. Transfer vegetables, chicken, and the stock to a bowl set in the ice bath; cool to room temperature. Cover; chill overnight.

When ready to serve, wash romaine, cut into bite-size pieces, and arrange on a platter. In a bowl, whisk vinegar, mustard, and honey. Slowly whisk in oil; set aside.

Discard any fat that has accumulated on top of chicken mixture. Shred chicken; place in a bowl. Drizzle a third of the vinaigrette over chicken. Sprinkle with 1/2 teaspoon salt and 1/8 teaspoon pepper; toss.

Arrange chicken over greens. Remove vegetables from stock; cut into bite-size pieces. Place in bowl used to toss chicken. Drizzle with half the remaining vinaigrette, sprinkle with remaining 1/2 teaspoon salt and 1/8 teaspoon pepper, toss, and arrange vegetables around chicken on platter. Drizzle with remaining vinaigrette; serve.
