01 - Preheat an outdoor grill or grill pan to medium-high heat, approximately 400°F.
02 - Brush the chicken breasts evenly with olive oil. Combine the smoked paprika, garlic powder, cumin, salt, and pepper, then rub the spice mixture over both sides of each breast.
03 - Place the seasoned chicken on the grill and cook for 6 to 7 minutes per side, until the internal temperature reaches 165°F. Transfer to a cutting board and rest for 5 minutes before slicing thinly against the grain.
04 - Grill the corn ears, either in their husks or wrapped in foil, for 10 to 12 minutes, rotating every few minutes for even charring. Once cool enough to handle, stand each ear upright and slice the kernels from the cob 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 mixing bowl, combine the grilled corn kernels, cherry tomatoes, red onion, cilantro, jalapeño, avocado, and crumbled cotija cheese. Toss gently to distribute evenly.
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 with the prepared dressing, and toss gently to coat all ingredients. Serve immediately, garnished with additional cilantro and cotija cheese if desired.
