Creating Perfect Calabrian Chili Grilled Chicken can be a fun and easy process by following these simple steps:

1. Prepare the Marinade: In a bowl, combine Calabrian chili paste, olive oil, lemon juice, minced garlic, salt, and pepper. Mix well until fully incorporated.
2. Marinate Chicken: Place the chicken breasts in a resealable bag or shallow dish. Pour the marinade over the chicken, ensuring that all pieces are well coated. Seal or cover and refrigerate for at least 1 hour, or up to overnight for a deeper flavor.
3. Preheat the Grill: Heat your grill to medium-high heat (about 375°F to 400°F).
4. Remove Chicken from Marinade: Take the chicken breasts out of the marinade, letting any excess drip off. Discard the leftover marinade.
5. Place Chicken on the Grill: Lay the chicken breasts on the grill grates. Close the lid and cook for 6-8 minutes on one side.
6. Flip the Chicken: After the first side has nice grill marks, flip the chicken breasts over and continue grilling for an additional 6-8 minutes.
7. Check for Doneness: The chicken is done when it reaches an internal temperature of 165°F (75°C). Use a meat thermometer for accuracy.
8. Rest the Chicken: Remove the chicken from the grill and let it rest for 5 minutes. This helps retain juices and flavor.
9. Garnish and Serve: Garnish with fresh parsley. Serve with optional lemon slices for added zest.

These steps will guide you in delivering an incredible dish that is brimming with flavor and perfect for any gathering.
