In a small bowl, whisk all of the dressing ingredients until well combined. In a medium bowl, add the chicken, eggs and bacon. Add the dressing to the chicken mixture and stir to combine. Add the blue cheese and stir again. Portion out the chicken mixture onto 4 lettuce cups. Top with fresh avocado and serve immediately.
Depending on how wet you like your chicken salad, you may not want to add all of the dressing.
