In a medium bowl, combine mayo (or Greek yogurt) with lime juice, chili powder, garlic powder, cumin, paprika, and a pinch of salt. Whisk until smooth and creamy.

In a large mixing bowl, add cooked shredded chicken, rinsed black beans, sweet corn, diced jalapeños, quartered cherry tomatoes, chopped red onion, and pepitas. Gently toss the ingredients together.

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

Scoop the salad into bowls or serve over lettuce or in a tortilla.
