In a large bowl, combine the cooked and shredded halal chicken breast, diced Hatch green chiles, red onion, cherry tomatoes, corn kernels, and cilantro.

In a separate small bowl, whisk together the mayonnaise, lime juice, cumin, salt, and pepper until smooth.

Pour the dressing over the chicken mixture and stir gently until well combined.

Taste and adjust seasoning if necessary, adding more salt, pepper, or lime juice as desired.

Serve immediately or refrigerate for at least 30 minutes to allow the flavors to meld.
