Making Fiesta Lime Chicken with Avocado is straightforward if you follow these easy steps:

1. Prepare the Marinade: In a bowl, whisk together lime juice, olive oil, minced garlic, cumin, chili powder, salt, and black pepper.
2. Marinate the Chicken: Place the chicken breasts in a zip-top bag or shallow dish. Pour the marinade over the chicken, ensuring each piece is well-coated. Seal the bag or cover the dish and refrigerate for at least 30 minutes.
3. Preheat the Grill or Pan: Heat a grill or a large skillet over medium-high heat.
4. Cook the Chicken: Remove the chicken from the marinade and discard the marinade. Grill or pan-fry the chicken for about 5-7 minutes on each side, or until fully cooked and internal temperature reaches 165°F (75°C).
5. Let it Rest: Once cooked, remove the chicken from the heat and let it rest for a few minutes before slicing.
6. Prepare the Avocado: While the chicken is resting, dice the avocado and chop the cilantro.
7. Assemble the Dish: Slice the chicken and arrange it on a serving platter. Top with diced avocado and sprinkle with chopped cilantro.
8. Serve with Lime Wedges: Add lime wedges on the side for an extra burst of flavor.
