Cook The Chicken: Season the chicken breasts with salt and pepper. Heat a grill or grill pan over medium-high heat. Grill the chicken for about 6-8 minutes per side, or until cooked through and no longer pink in the center. Once cooked, let the chicken rest for a few minutes, then slice it into thin strips.
Prepare the Salad: In a large salad bowl, combine the mixed greens, diced avocado, halved cherry tomatoes, corn kernels, chopped red onion, sliced black olives, and chopped cilantro. Toss the salad gently to combine all the ingredients evenly.
Make the Dressing: In a small bowl, whisk together the olive oil, lime juice, minced garlic, honey, Greek yogurt, and Dijon mustard until well combined. Season the dressing with salt and pepper to taste.
Assemble the Salad: Add the sliced grilled chicken to the salad bowl. Pour the dressing over the salad and toss gently until everything is coated evenly with the dressing.
Serve:
Divide the California chicken salad among serving plates or bowls. Sprinkle crumbled feta cheese over the top of each salad. Serve immediately and enjoy!
