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 smoked paprika, garlic powder, cumin, salt, and pepper in a small dish, then rub the spice mixture over both sides of each breast until well coated.
03 - Place the seasoned chicken onto the hot grill and cook for 6 to 7 minutes per side, until the internal temperature registers 165°F. Transfer to a cutting board and let rest for 5 minutes before slicing thinly against the grain.
04 - While the chicken rests, grill the corn ears (in husks or wrapped in foil) for 10 to 12 minutes, rotating every few minutes, until lightly charred on all sides. Stand each ear upright and slice the kernels off the cob with a sharp knife. If using frozen corn, sear the kernels in a hot skillet for 3 to 4 minutes until blistered.
05 - In a large mixing bowl, combine the grilled corn kernels, halved cherry tomatoes, diced red onion, chopped cilantro, minced jalapeño, diced 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 completely smooth and well blended.
07 - Add the sliced grilled chicken to the salad bowl, drizzle the dressing over the top, and toss gently to coat all ingredients. Serve immediately, garnished with additional cilantro and cotija cheese if desired.
