Who can say no to layers of chicken, veggies, shrimp and bacon? Since the dressing does not cover all the greens, it is a perfect salad to make ahead of time.
Place sliced lettuce in the bottom of a 14-cup glass salad bowl or trifle dish. Pack down slightly.
On top of lettuce, neatly layer tomatoes, chicken, avocados, red onion and shrimp. Press down lightly to compress.
Spread with dressing. Refrigerate at least 1 hour; sprinkle with bacon just before serving.
