In a large bowl, combine the cooked chicken, black beans, corn, red bell pepper, red onion, avocado, cherry tomatoes, 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 salad mixture and toss gently to combine, ensuring all ingredients are coated.
Taste and adjust seasoning if necessary, adding more salt, pepper, or lime juice as desired.
Serve immediately or refrigerate for 30 minutes to allow flavors to meld before serving.
