1. Preheat your grill or grill pan over medium-high heat. Lightly oil the grates to prevent sticking.
2. In a small bowl, combine the olive oil, smoked paprika, garlic powder, salt, and black pepper. Rub this mixture evenly over both sides of the chicken breasts.
3. Place the chicken on the grill and cook for about 6-7 minutes per side, or until the internal temperature reaches 165°F (75°C) and the juices run clear. You’re looking for nice grill marks and a slightly charred exterior without drying out the chicken.
4. While the chicken cooks, prepare the dressing by whisking together olive oil, red wine vinegar, Dijon mustard, honey, salt, and pepper in a small bowl. Taste and adjust seasoning as needed.
5. Once the chicken is done, transfer it to a cutting board and let it rest for 5 minutes. Resting helps keep the juices locked in—a trick I picked up after many early attempts at dry chicken.
6. Slice the chicken into thin strips or bite-sized pieces.
7. In a large salad bowl, combine the mixed greens, cherry tomatoes, cucumber slices, red onion, and shredded carrots. Toss gently with about half of the dressing.
8. Top the salad with the sliced grilled chicken, crumbled feta, and toasted nuts, then drizzle with the remaining dressing.
9. Give the salad one last gentle toss right before serving to distribute flavors.

From personal experience, the key to success here is not rushing the chicken and letting it rest properly. Also, don’t be shy with the dressing—it ties everything together and brings out the brightness of the veggies.
