Preheat your grill to medium heat.
Grill the corn until you have visible char marks.
Cook the chicken on the grill until fully cooked.
Allow the chicken and corn to cool slightly before chopping and shredding.
In a mixing bowl, combine shredded chicken, grilled corn, diced red bell pepper, finely chopped red onion, and diced avocado.
In a separate bowl, whisk together lime juice, olive oil, salt, and pepper to form the dressing.
Pour the dressing over the salad and toss gently.
Add chopped cilantro and mix one last time before serving.
