In a large bowl, combine the shredded chicken, black beans, corn, red bell pepper, red onion, avocado, cilantro, and cherry tomatoes.
In a separate small bowl, whisk together the lime juice, olive oil, cumin, chili powder, salt, and pepper until well combined.
Pour the dressing over the salad mixture and gently toss to coat all ingredients evenly.
Taste and adjust seasoning if necessary.
Chill the salad in the refrigerator for at least 30 minutes before serving to allow the flavors to meld.
Serve chilled or at room temperature.
