01 - Whisk together lime juice, honey, soy sauce, olive oil, garlic, salt, pepper, red pepper flakes, and lime zest until well combined. Stir in chopped cilantro.
02 - Place chicken breasts in a large ziplock bag or shallow dish. Pour marinade over chicken, ensuring all pieces are evenly coated. Seal or cover and marinate in refrigerator for at least 30 minutes, up to 2 hours for deeper flavor.
03 - Preheat grill to medium-high heat. Lightly oil the grates to prevent sticking.
04 - Remove chicken from marinade and discard used marinade. Grill chicken for 5 to 7 minutes per side, or until cooked through and internal temperature reaches 165°F.
05 - Transfer chicken to a plate, cover loosely with foil, and let rest for 5 minutes. Garnish with extra cilantro and serve with lime wedges if desired.
