01 - Combine mango, olive oil, lime juice, honey, garlic, ginger, chili flakes, salt, and black pepper in a blender or food processor. Blend until completely smooth to create a uniform marinade.
02 - Set aside 1/4 cup of the prepared marinade in a separate container for brushing during grilling and serving as a finishing sauce.
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. Seal and refrigerate for at least 1 hour, or overnight for maximum flavor penetration.
04 - Preheat grill to medium-high heat (approximately 400°F). Lightly oil the grates with a high-heat cooking oil or paper towel dipped in vegetable oil to prevent sticking.
05 - Take chicken out of the marinade, allowing excess liquid to drip off. Discard the used marinade to prevent cross-contamination.
06 - Place chicken on the preheated grill. Cook for 6 to 8 minutes per side, brushing with the reserved marinade during the final 2 minutes of cooking. Continue until internal temperature reaches 165°F when tested with a meat thermometer.
07 - Transfer grilled chicken to a cutting board or platter. Let rest for 5 minutes to allow juices to redistribute throughout the meat.
08 - Slice chicken against the grain into strips. Garnish generously with chopped fresh cilantro and serve with lime wedges alongside. Drizzle any remaining reserved marinade over the top.
