4 large skinless boneless chicken breast halves (about 6 to 7 ounces each)
Directions
Mix cherry tomatoes, olives, 2 tablespoons extra-virgin olive oil, mint, and vinegar in medium bowl. Gently stir in feta cheese. Season relish to taste with salt and pepper.
Prepare barbecue (medium-high heat). Brush chicken on both sides with remaining 1 tablespoon extra-virgin olive oil; sprinkle with salt and pepper. Grill chicken just until cooked through, about 7 minutes per side. Transfer chicken to plates and slice, if desired. Top with relish and serve.
