Place the chicken breasts into the Greek salad dressing. You can use store-bought or make your own. Marinate for at least 2 hours, but preferably overnight.
Preheat your grill to 350°F. Place the chicken onto the grill.
Cook for 6-8 minutes per side, or until the internal temperature is 165°F.
Remove from the grill and set aside. Let rest for 10 minutes.
While the chicken is grilling, prep the rest of the ingredients and mix in a large bowl.
Cube the chicken breast and toss with the rest of the salad ingredients. Toss with the additional salad dressing.
