Ingredients

For dressing:
3 tablespoons red-wine vinegar
1 tablespoon fresh lemon juice
2 teaspoons Dijon mustard
1 small clove garlic, minced
1/2 teaspoon salt
1/2 teaspoon freshly ground black pepper
1/2 cup extra-virgin olive oil

For salad:
3 skinless boneless chicken breast halves (1 3/4 pound)

2 ripe Hass or other seasonal avocados
1 head romaine, cut crosswise into 1/2-inch wide slices (8 cups)
6 bacon slices, cooked until crisp, drained, and finely chopped
3 medium tomatoes (3/4 pound), seeded and cut into 1/2-inch pieces
2 to 3 ounces Roquefort, crumbled (1/2 to 3/4 cup)
2 bunches watercress, coarse stems discarded
2 hard-boiled large eggs, sliced with an egg slicer
1/4 cup finely chopped fresh chives

Directions

Make dressing: Whisk
together all dressing ingredients except oil in a bowl, then add oil in a slow stream,
whisking until emulsified.

Make salad: Bring 5 cups water to a simmer in a 2-quart saucepan, then simmer chicken,
uncovered, 6 minutes. Remove pan from heat and cover, then let stand until chicken is
cooked through, about 15 minutes. Transfer the chicken to a cutting board and cool
completely. Cut into 1/2-inch cubes.

Halve pit and peel avocados, then cut into 1/2-inch cubes.

Spread romaine over bottom of a 6- to 8-quart glass bowl and top with an even layer of
chicken. Sprinkle bacon over chicken, then continue layering with tomatoes, cheese (to
taste), avocados, watercress, eggs, and chives.

Just before serving, pour dressing over salad and toss.

Cook's note: Dressing can be made and salad assembled 1 hour ahead and chilled separately,
covered.
