Creating the perfect Summer Berry Chicken Salad is easy if you follow these steps:

1. Prepare the Chicken: Season the chicken breasts with salt and pepper. Drizzle olive oil over them for added flavor.

2. Grill the Chicken: Preheat your grill to medium-high heat. Grill the chicken for about 6-8 minutes per side or until fully cooked (internal temperature should reach 165°F).

3. Rest and Slice: Once cooked, remove the chicken from the grill and allow it to rest for about 5 minutes. After resting, slice the chicken into thin strips.

4. Prepare the Salad Base: In a large bowl, combine the mixed salad greens. You can choose any combination you like, but the greens should be fresh and crisp.

5. Add Berries and Nuts: Layer the sliced strawberries, blueberries, and blackberries over the greens. Sprinkle the nuts on top for crunch.

6. Include Chicken and Cheese: Add sliced grilled chicken and crumbled feta cheese if desired.

7. Dress the Salad: Drizzle the balsamic vinaigrette over the salad and toss gently until everything is coated.

8. Serve Immediately: Plate the salad, ensuring each serving gets an equal share of chicken and berries.
