Prepare the Salsa: In a medium mixing bowl, combine the diced mango, fresh pineapple, red bell pepper, finely chopped red onion, and minced jalapeño (if using). Add the lime juice along with a pinch of salt and freshly ground black pepper. Gently toss all ingredients together to mix well, then set aside to allow the flavors to meld together—about 10-15 minutes.
Season the Chicken: Using paper towels, pat the chicken breasts dry to remove excess moisture. Drizzle olive oil over both sides of each chicken breast, then generously season with salt and freshly ground black pepper, ensuring an even coating.
Cook the Chicken: Preheat your grill or a grill pan over medium-high heat. Once hot, place the seasoned chicken breasts onto the grill. Grill each breast for approximately 6-7 minutes on one side, flip and continue grilling for another 6-7 minutes, or until the chicken is cooked through and has an internal temperature of 165°F (75°C). Remove the chicken from the heat and allow it to rest for about 5 minutes to lock in the juices.
Assemble the Dish: With a sharp knife, slice the grilled chicken breasts into tender strips. Begin plating by laying the slices in the center of a serving dish, fanning them out slightly. Generously spoon the vibrant Mango Pineapple Salsa over the sliced chicken, letting the colorful toppings cascade over the edges.
Garnish and Serve: Finish the dish by sprinkling freshly chopped cilantro over the salsa for an aromatic touch and appealing color. Serve with lime wedges on the side for an extra burst of freshness and zing.
Notes
For added visual appeal, consider serving the dish on a colorful platter and arranging extra lime wedges around the edges.
