In a large bowl, combine the shredded chicken, black beans, corn, red bell pepper, avocado, cherry tomatoes, red onion, and cilantro.
In a separate small bowl, whisk together the lime juice, olive oil, chili powder, cumin, salt, and pepper until well combined.
Pour the dressing over the chicken mixture and gently toss to coat all ingredients evenly.
Taste and adjust seasoning if necessary. If you prefer a spicier kick, add a pinch of cayenne pepper.
Chill the salad in the refrigerator for at least 30 minutes to allow the flavors to meld.
Serve the salad on its own or with tortilla chips for added crunch.
