Rinse lettuce thoroughly, remove the core and remove any wilted outer leaves. Cut the head of lettuce in half, then in half again to create 4 equal wedges. Place each wedge in a wide-rimmed bowl or onto a large dinner plate.
To each wedge add equally: red onion, chopped eggs, grape tomatoes, bacon crumbles, crispy onions and shredded Cooper Sharp Black Pepper cheese.
Top each wedge salad with peppercorn ranch dressing, then garnish the plate or bowl with avocado slices and sliced chicken.
