01 - In a mixing bowl, whisk together the olive oil, lime juice, cumin, smoked paprika, salt, and pepper. Add the chicken breasts and turn to coat evenly. Cover and let marinate for at least 15 minutes at room temperature or up to 2 hours in the refrigerator.
02 - In a medium bowl, combine the diced pineapple, diced mango, chopped red onion, diced bell pepper, cilantro, minced jalapeño, and lime juice. Season with salt to taste, stir gently to combine, and refrigerate until ready to serve.
03 - Rinse the jasmine rice under cold running water until the water runs clear. In a saucepan, bring the coconut milk, water, and salt to a boil. Stir in the rice, reduce heat to low, cover tightly, and simmer for 15 minutes or until all liquid is absorbed. Remove from heat and fluff with a fork.
04 - Preheat a grill or grill pan over medium-high heat. Remove the chicken from the marinade and grill for 5 to 7 minutes per side, or until the internal temperature reaches 165°F and juices run clear. Transfer to a cutting board and let rest for 5 minutes before slicing.
05 - Divide the coconut rice among four plates. Arrange the sliced chicken over the rice and spoon the pineapple-mango salsa generously over the top. Garnish with lime wedges and fresh cilantro sprigs. Serve immediately.
