In a medium bowl, I whisk together the mayo or Greek yogurt, lime juice, chili powder, garlic powder, cumin, paprika, and salt until the dressing looks smooth and creamy. This becomes the flavor base for the entire salad.
In a large bowl, I add shredded chicken, black beans, corn, jalapeños, cherry tomatoes, red onion, and pepitas. Everything gets tossed lightly so the ingredients are evenly distributed before adding the dressing.
I pour the dressing over the salad and gently mix until everything is well-coated. After a quick taste test, I adjust the salt or spice if needed. You can serve it right away or refrigerate it to let the flavors deepen.
