Creating Key West Grilled Chicken with Tropical Citrus Marinade is straightforward when you follow these simple steps:

1. Prepare the Marinade: In a bowl, whisk together the orange juice, lime juice, olive oil, honey, minced garlic, cumin, salt, and black pepper until well combined.
2. Marinate the Chicken: Place the chicken breasts in a resealable plastic bag or shallow dish. Pour the marinade over the chicken, ensuring it is fully coated. Seal the bag or cover the dish, and refrigerate for at least 30 minutes (or up to 2 hours for more flavor).
3. Preheat the Grill: Preheat your grill to medium-high heat, around 400°F (200°C).
4. Grill the Chicken: Remove the chicken from the marinade, allowing excess marinade to drip off. Place the chicken on the grill and cook for 6-8 minutes on each side, or until the internal temperature reaches 165°F (75°C) and the chicken is no longer pink in the center.
5. Rest and Serve: Once cooked, remove the chicken from the grill and let it rest for a few minutes. Garnish with fresh cilantro if desired, and serve with your choice of sides.
