1Preheat your grill to medium-high heat.
Season the chicken breast with 1/2 teaspoon of salt and 1/4 teaspoon of black pepper.
Grill the chicken breast for 6-7 minutes on each side, or until fully cooked and the internal temperature reaches 165°F (75°C).
While the chicken is grilling, prepare the salad. In a large bowl, combine the mixed greens, cherry tomatoes, cucumber, and red onion.
In a small bowl, whisk together the olive oil, lemon juice, remaining salt, and black pepper to make the dressing.
Once the chicken is cooked, let it rest for 5 minutes before slicing it into thin strips.
Add the sliced chicken to the salad bowl.
Drizzle the dressing over the salad and toss to combine.
Sprinkle the feta cheese on top of the salad.
Serve immediately and enjoy your Grilled Chicken Salad.
