01 - Combine diced mango, 2 tablespoons olive oil, 2 tablespoons lime juice, 2 teaspoons honey, minced garlic, cumin, smoked paprika, salt, and pepper in a blender. Process until completely smooth, about 30 seconds.
02 - Place chicken breasts in a large resealable plastic bag or shallow glass dish. Pour the mango marinade over the chicken, turning to coat all sides evenly. Refrigerate for 30 minutes, or up to 2 hours for deeper flavor penetration.
03 - Whisk together 2 tablespoons lime juice, 1 tablespoon honey, red pepper flakes, chopped cilantro, 1 tablespoon olive oil, and a pinch of salt in a small bowl until honey dissolves completely. Set aside at room temperature.
04 - Heat grill to medium-high temperature, approximately 400°F. Clean grates and lightly oil to prevent sticking.
05 - Remove chicken from marinade, letting excess drip off. Discard used marinade. Grill chicken for 6 to 8 minutes per side, until internal temperature reaches 165°F and juices run clear when pierced.
06 - Transfer grilled chicken to a serving platter. Spoon chili lime drizzle generously over each piece. Sprinkle with additional fresh cilantro and arrange lime wedges alongside. Serve immediately while hot.
