01 - In a medium bowl, whisk together the honey, fresh lime juice, lime zest, olive oil, chili powder, smoked paprika, ground cumin, garlic powder, salt, black pepper, and crushed red pepper flakes until smooth and well combined.
02 - Place the chicken breasts in a large resealable bag or shallow dish. Pour the marinade over the chicken, ensuring each piece is evenly coated on all sides. 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 the chicken from sticking during cooking.
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 (74°C) and the juices run clear.
05 - Transfer the grilled chicken to a platter and let it rest for 5 minutes to allow the juices to redistribute before slicing.
06 - Scatter chopped fresh cilantro over the sliced chicken and serve with lime wedges on the side.
