Here is your detailed guide to preparing Fiesta Lime Chicken, step-by-step:

1. Prepare Marinade: In a bowl, whisk together lime juice, olive oil, minced garlic, chili powder, cumin, paprika, salt, pepper, and cayenne pepper.
2. Marinate Chicken: Place the chicken breasts in a resealable plastic bag or a shallow dish. Pour the marinade over the chicken, ensuring it’s well coated. Seal or cover and let it marinate in the refrigerator for at least 30 minutes.
3. Preheat Grill: Preheat your grill to medium-high heat.
4. Remove Chicken from Marinade: Take the marinated chicken out of the bag or dish, allowing any excess marinade to drip off.
5. Grill Chicken: Place the chicken on the preheated grill. Grill for about 6-7 minutes on each side or until the internal temperature reaches 165°F (74°C).
6. Rest Chicken: Once cooked, remove the chicken from the grill and let it rest for 5 minutes before slicing. This helps retain its juices.
7. Garnish and Serve: Sprinkle chopped cilantro over the sliced chicken for a fresh garnish.

Following these steps will ensure you create a delightful dish that tantalizes the palate and leaves everyone satisfied.
