01 - In a blender or food processor, combine the diced mango, pineapple, honey, lime juice, soy sauce, minced garlic, grated ginger, and smoked paprika. Blend until completely smooth.
02 - Pour 1/4 cup of the blended marinade into a separate bowl and set aside for basting during grilling.
03 - Place chicken breasts in a resealable plastic bag or shallow dish. Pour the remaining marinade over the chicken, ensuring all pieces are thoroughly coated. Refrigerate for at least 1 hour, or up to 4 hours for deeper flavor penetration.
04 - Preheat grill to medium-high heat. Oil the grates generously to prevent the chicken from sticking.
05 - Remove chicken from the marinade and pat lightly dry with paper towels. Brush both sides with olive oil and season with salt and freshly ground black pepper.
06 - Grill chicken for 6 to 7 minutes per side, basting with the reserved marinade during the final minutes of cooking. Cook until the internal temperature reaches 165°F (74°C) and juices run clear.
07 - Transfer chicken to a cutting board and rest for 5 minutes. Slice and serve garnished with fresh cilantro, extra mango and pineapple pieces, and lime wedges.
