Creating Juicy Spicy Grilled Cuban Chicken is simple when you follow these easy steps:

1. Prepare the Marinade: In a bowl, combine lime juice, orange juice, minced garlic, oregano, cumin, paprika, cayenne pepper, olive oil, salt, and pepper. Whisk until well combined.

2. Marinate the Chicken: Place the chicken breasts in a large zip-top plastic bag. Pour the marinade over the chicken, ensuring each piece is well-coated. Seal the bag and refrigerate for at least 1 hour, or overnight for the best results.

3. Preheat the Grill: About 15 minutes before grilling, preheat your grill on medium-high heat. Lightly oil the grill grates to prevent the chicken from sticking.

4. Grill the Chicken: Remove the chicken from the marinade and let any excess drip off. Place the chicken on the preheated grill. Cook for 6-7 minutes on each side, or until internal temperature reaches 165°F (75°C).

5. Rest the Chicken: Remove the chicken from the grill and let it rest for about 5 minutes. This allows the juices to redistribute, keeping the chicken succulent.

6. Garnish and Serve: Before serving, garnish the chicken with fresh cilantro for an added burst of flavor.

This straightforward method will ensure that your Juicy Spicy Grilled Cuban Chicken turns out perfectly every time.
