Rinse and thoroughly dry the salad greens. Chop or tear into bite-sized pieces and place them in a large salad bowl.
Cook the bacon in a skillet over medium heat until crispy. Drain on a paper towel and once cooled, crumble into small pieces.
In a small bowl, whisk together the apple cider vinegar, olive oil, Dijon mustard, Worcestershire sauce, and minced garlic until well combined. Season with salt and pepper to taste.
Arrange the mixed salad greens evenly in the large bowl. On top of the greens, arrange rows of diced chicken, bacon crumbles, chopped eggs, diced avocado, cherry tomatoes, crumbled blue cheese, and sliced red onion.
Drizzle the dressing over the arranged salad. For an even distribution, you can toss the salad gently before serving or serve the dressing on the side for individual dressing to taste.
Serve immediately as a main dish or side salad.
