01 - Combine mango, olive oil, lime juice, honey, garlic, ginger, chili flakes, salt, and black pepper in a blender. Process until completely smooth to create a uniform marinade consistency.
02 - Transfer 1/4 cup of the blended marinade to a separate container. Set aside for brushing during grilling and serving.
03 - Place chicken breasts in a large resealable plastic bag or shallow glass dish. Pour the remaining marinade over the chicken, ensuring each piece is thoroughly coated. Refrigerate for minimum 1 hour, maximum overnight for optimal flavor penetration.
04 - Heat grill to medium-high temperature (400°F). Lightly coat the grates with oil to prevent sticking.
05 - Remove chicken from the marinade, allowing excess liquid to drip away. Discard the used marinade completely.
06 - Grill chicken for 6 to 8 minutes per side. During the final 2 minutes of cooking, brush with the reserved marinade. Continue grilling until internal temperature reaches 165°F.
07 - Transfer chicken from grill to a cutting board. Let rest for 5 minutes to allow juices to redistribute throughout the meat.
08 - Slice chicken against the grain. Sprinkle with chopped cilantro and arrange lime wedges alongside for squeezing over the top.
