01 - In a medium bowl, whisk together the honey, lime juice, lime zest, olive oil, chili powder, smoked paprika, cumin, garlic powder, salt, black pepper, and red pepper flakes until well blended.
02 - Place the chicken breasts in a large resealable bag or shallow dish. Pour the marinade over the chicken, making sure every piece is evenly coated. Seal the bag or cover the dish and refrigerate for at least 1 hour, or up to 8 hours for deeper flavor penetration.
03 - Preheat an outdoor grill or grill pan to medium-high heat. Lightly oil the grates to prevent sticking.
04 - Remove the chicken from the marinade, allowing any excess to drip off. Place the chicken on the hot grill and cook for 6 to 7 minutes per side, until the internal temperature reaches 165°F and the juices run clear.
05 - Transfer the grilled chicken to a platter and let it rest for 5 minutes before slicing to allow the juices to redistribute.
06 - Sprinkle chopped fresh cilantro over the sliced chicken and serve alongside lime wedges.
