01 - In a mixing bowl, whisk together honey, olive oil, lime zest, lime juice, minced garlic, salt, black pepper, and ground cumin until fully combined.
02 - Place chicken breasts in a resealable bag or shallow dish. Pour marinade over the chicken, ensuring all pieces are coated evenly. Cover and refrigerate for a minimum of 20 minutes and up to 4 hours.
03 - While the chicken marinates, combine diced mango, chopped red onion, diced red bell pepper, finely chopped jalapeño, lime juice, and fresh cilantro in a bowl. Season with salt and pepper. Toss gently and set aside.
04 - Preheat a grill or grill pan to medium-high heat.
05 - Remove chicken breasts from marinade, discarding excess marinade. Grill the chicken for 6 to 7 minutes per side, or until cooked through and juices run clear with an internal temperature of 165°F.
06 - Transfer grilled chicken to a plate and allow it to rest for 5 minutes before serving.
07 - Place each chicken breast on a serving plate and top generously with mango salsa. Garnish with lime wedges and additional fresh cilantro leaves as desired.
