Step 1

Whisk vinegar, shallot, mustard, pepper and salt in a small bowl to combine. Whisk in oil until combined. Place salad greens in a large bowl. Add half of the dressing and toss to coat.

Step 2

Divide the greens among 4 plates. Arrange equal portions of chicken, egg, tomatoes, cucumber, avocado, bacon and blue cheese (if using) on top of the lettuce. Drizzle the salads with the remaining dressing.
