In a large bowl, add chopped lettuce as the base.
Layer chicken, beans, corn, tomatoes, bell pepper, avocado, red onion, cheese, and cilantro on top.
Drizzle with dressing and toss everything to coat evenly.
Sprinkle crushed tortilla chips on top just before serving.
Serve immediately or chill for 15 minutes if you want it extra refreshing.
