01 - In a medium bowl, whisk together lime juice, lemon juice, olive oil, honey, garlic, soy sauce, salt, black pepper, cumin, thyme, and red pepper flakes until fully combined.
02 - Place chicken breasts in a large resealable plastic bag or shallow dish. Pour marinade over the chicken, seal, and refrigerate for at least 30 minutes or up to 2 hours for deeper flavor penetration.
03 - Preheat grill to medium-high heat. Lightly oil the grates to prevent sticking.
04 - Remove chicken from marinade, letting excess drip off. Discard leftover marinade to avoid cross-contamination.
05 - Place chicken on the grill. Grill 5–6 minutes per side, or until chicken is cooked through and internal temperature reaches 165°F.
06 - Transfer chicken to a platter. Rest for 5 minutes to allow juices to redistribute, then garnish with chopped cilantro and serve with lime wedges.
