How to Make It
Stir together olive oil, parsley, basil, cilantro, garlic, lemon zest, lemon juice, salt, crushed red pepper, and black pepper in a bowl, and transfer to a large ziplock plastic bag. Remove 2 tablespoons of mixture, and reserve. Add chicken to bag; seal bag, and toss to coat. Chill 1 to 2 hours, turning chicken once.
Preheat grill to medium-high (400°F to 450°F). Remove chicken from marinade; discard marinade. Let chicken stand at room temperature 15 minutes. Place chicken on oiled grates; grill, covered, until a thermometer registers 160°F when inserted in thickest portion of chicken breast, 5 to 6 minutes per side. Remove chicken from grill, and let rest 10 minutes. Drizzle with reserved 2 tablespoons marinade.
