In a medium mixing bowl, combine mayo or Greek yogurt with fresh lime juice, chili powder, garlic powder, cumin, paprika, and salt. Whisk until creamy and well-blended.

In a large mixing bowl, add shredded chicken, black beans, and corn. Toss in chopped jalapeños, quartered cherry tomatoes, finely chopped red onion, and pepitas. Mix until evenly distributed.

Pour the creamy dressing over the mixed salad ingredients. Gently fold the dressing in, ensuring all components are coated without mashing.

Serve immediately for the freshest taste or use in sandwiches, lettuce wraps, or tortillas.
