In a large bowl, whisk together the coconut milk, lime juice, soy sauce, honey, minced garlic, ground ginger, red pepper flakes, salt, and pepper until well combined.
Add the chicken thighs to the marinade, ensuring they are fully coated. Cover and refrigerate for at least 1 hour, or up to overnight for maximum flavor.
Preheat your grill or a grill pan over medium-high heat.
Remove the chicken from the marinade, allowing excess marinade to drip off. Discard the marinade.
Grill the chicken for about 6-7 minutes per side, or until the internal temperature reaches 165°F.
Once cooked, remove the chicken from the grill and let it rest for 5 minutes.
Slice the chicken and serve it garnished with fresh cilantro and lime wedges.
