In a medium bowl, mix together the mayo (or Greek yogurt), fresh lime juice, chili powder, garlic powder, cumin, paprika, and salt until smooth.

In a large bowl, toss together the cooked shredded chicken, black beans, corn, chopped jalapeños, quartered cherry tomatoes, finely chopped red onion, and pepitas.

Drizzle the prepared dressing over the salad mixture and gently stir until everything is thoroughly coated.

Serve the salad immediately on its own, in sandwiches or wraps, or over a bed of lettuce.
