In a medium bowl, whisk together mayo or Greek yogurt with fresh lime juice, chili powder, garlic powder, cumin, paprika, and salt until smooth.

In a large mixing bowl, add cooked shredded chicken, black beans, corn, jalapeños, tomatoes, red onion, and pepitas. Toss gently to combine.

Pour the dressing over the salad mixture and fold gently until everything is coated.

Serve immediately on its own, in sandwiches, or on a bed of lettuce.
