01 - In a medium bowl, whisk together honey, lime juice, lime zest, olive oil, garlic, soy sauce, chili powder, cayenne pepper, smoked paprika, salt, and black pepper until well combined.
02 - Place chicken breasts in a large resealable bag or shallow dish. Pour the marinade over the chicken, ensuring all pieces are well coated. Seal and refrigerate for at least 30 minutes, up to 4 hours for deeper flavor.
03 - Preheat grill or grill pan over medium-high heat. Remove chicken from marinade, allowing excess to drip off. Discard remaining marinade.
04 - Grill chicken breasts for 6–8 minutes per side, or until cooked through and internal temperature reaches 165°F.
05 - Remove from grill, let rest for 5 minutes, then slice. Garnish with fresh cilantro and lime wedges before serving, if desired.
