01 - Preheat a grill or grill pan to medium-high heat.
02 - Brush the chicken breasts with olive oil, then rub evenly with smoked paprika, garlic powder, cumin, salt, and pepper.
03 - Grill the chicken for 6 to 7 minutes per side until cooked through and the internal temperature reaches 165°F. Remove from the grill and let rest for 5 minutes, then slice thinly against the grain.
04 - Grill the corn ears (in husks or wrapped in foil) for 10 to 12 minutes, rotating occasionally, until lightly charred. Cut the kernels off the cobs with a sharp knife. If using frozen corn, char the kernels in a hot skillet for 3 to 4 minutes instead.
05 - In a large bowl, combine the grilled corn kernels, halved cherry tomatoes, diced red onion, chopped cilantro, jalapeño, diced avocado, and crumbled cotija cheese.
06 - In a small bowl, whisk together the Greek yogurt, mayonnaise, fresh lime juice, honey, chili powder, and salt until smooth and well blended.
07 - Add the sliced chicken to the salad bowl, drizzle the dressing over the top, and toss gently to coat everything evenly.
08 - Serve immediately, garnished with additional cilantro and crumbled cotija cheese if desired.
