Step 1: Marinate the Chicken In a small bowl, combine lime juice, pineapple juice, cilantro, olive oil, ¼ teaspoon cumin, and salt. This citrusy mixture will infuse the chicken with flavor and tenderize it for optimal grilling results. Remove 5 tablespoons of this juice mixture to a sealable plastic bag. Set the remaining juice mixture aside (for salsa).

Step 1: Add minced garlic, the remaining ½ teaspoon cumin, and chicken breasts to the bag. Seal the bag and toss to coat the chicken thoroughly. Make sure each piece is well-covered with the marinade for maximum flavor penetration. Refrigerate for at least 30 minutes, or up to several hours. The longer the chicken marinates, the more flavorful it will become.

Step 2: Prepare the Pineapple Avocado Salsa In a separate bowl, combine diced pineapple, diced avocado, and chopped red onion. Pour the reserved lime juice mixture (from step 1) over the fruit and onion. This clever technique uses part of the marinade as the dressing for the salsa, creating perfect flavor harmony between all components of the dish.

Step 2: Toss gently to coat all ingredients. Be careful not to mash the avocado pieces while mixing. Cover and refrigerate until ready to serve. The lime juice in the mixture will help prevent the avocado from browning while keeping all flavors fresh and vibrant.

Step 3: Grill the Chicken Clean and preheat the grill to medium heat. A properly preheated grill ensures beautiful grill marks and prevents the chicken from sticking. Remove chicken from the marinade bag and discard the used marinade. Never reuse marinade that has been in contact with raw chicken for food safety reasons.

Step 3: Grill the chicken breasts over medium heat for about 6 minutes per side, or until cooked through. The exact time will vary depending on the thickness of your chicken breasts. Flip the chicken only once to develop good grill marks. Ensure the internal temperature reaches 165°F (74°C) using a meat thermometer. This is the safest temperature for chicken consumption while keeping it juicy and flavorful.

Step 4: Serve with Style Transfer the cooked grilled chicken breasts to plates and let them rest for 3-5 minutes. This allows the juices to redistribute throughout the meat, resulting in more tender and flavorful chicken. Generously top each chicken breast with the prepared pineapple avocado salsa.

Step 4: For an extra touch of elegance, garnish with additional fresh cilantro and perhaps a lime wedge on the side. Serve immediately while the chicken is still warm and the salsa is fresh and vibrant.
