In a spacious mixing bowl, whisk together the olive oil, garlic powder, ground cumin, salt, and freshly ground black pepper. Add the chicken breasts, ensuring they are thoroughly coated in the marinade. Cover the bowl with plastic wrap or a lid and place it in the refrigerator for a minimum of 30 minutes (or up to 4 hours for a deeper flavor infusion).
While the chicken is marinating, gather a separate mixing bowl. Combine the diced pineapple, red bell pepper, minced jalapeño, finely chopped red onion, coarsely chopped cilantro, lime juice, and lime zest. Gently toss all the ingredients together until well mixed. Set the salsa aside to let the flavors combine and develop.
Preheat your grill or grill pan to medium-high heat. Once heated, take the chicken breasts out of the marinade, allowing any excess to drip off, and place them on the grill. Cook for approximately 6-7 minutes on each side, or until the chicken is fully cooked through and has an internal temperature of 165°F (75°C).
After grilling, remove the chicken from the grill and let it rest for about 2-3 minutes. This allows the juices to redistribute. Slice each chicken breast and generously spoon the fresh pineapple salsa over the top.
Present the Tropical Pineapple Salsa Chicken beautifully on a plate garnished with additional cilantro if desired. Serve alongside a bed of rice, fluffy quinoa, or a vibrant fresh green salad for a well-rounded and satisfying meal.
Notes
For a milder salsa, remove the seeds from the jalapeño pepper.
