In a large mixing bowl, combine the cooked chicken, black beans, corn, red bell pepper, cherry tomatoes, avocado, red onion, cilantro, and shredded cheese.
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 toss gently to coat all ingredients evenly.
Taste and adjust seasoning if necessary. If desired, chill the salad in the refrigerator for 30 minutes before serving to enhance the flavors.
Serve the salad in bowls or on a bed of greens.
