In a medium mixing bowl, combine the mayo or Greek yogurt with lime juice, chili powder, garlic powder, cumin, paprika, and salt. Mix until the dressing is smooth.

In a large bowl, add the cooked shredded chicken, drained black beans, corn, jalapeños, cherry tomatoes, red onion, and pepitas. Stir gently to mix.

Pour the dressing over the salad mixture and fold everything together until nicely coated.

Serve the salad in bowls or on a platter, optionally in lettuce cups or wraps.
