01 - Combine mango, olive oil, lime juice, honey, garlic, ginger, chili flakes, salt, and black pepper in a blender or food processor. Blend until smooth to create a uniform marinade consistency.
02 - Set aside 1/4 cup of the blended marinade in a separate container for brushing during grilling and serving at the table.
03 - Place chicken breasts in a large resealable bag or shallow dish. Pour the remaining marinade over the chicken, ensuring each piece is thoroughly coated. Refrigerate for at least 1 hour, or overnight for more intense flavor penetration.
04 - Heat grill to medium-high temperature (400°F). Lightly oil the grates to prevent sticking and ensure clean release of the chicken.
05 - Remove chicken from the marinade, allowing excess liquid to drip off. Discard the used marinade to prevent cross-contamination.
06 - Grill chicken for 6-8 minutes per side, brushing with the reserved marinade during the final 2 minutes of cooking. Cook until internal temperature reaches 165°F for safe consumption.
07 - Transfer grilled chicken to a cutting board and let rest for 5 minutes to allow juices to redistribute. Slice crosswise and sprinkle generously with chopped fresh cilantro.
08 - Arrange sliced chicken on a serving platter and accompany with fresh lime wedges for squeezing over the top.
