01 - In a mixing bowl, combine honey, olive oil, lime zest, lime juice, minced garlic, salt, black pepper, and ground cumin. Whisk until thoroughly blended.
02 - Arrange chicken breasts in a resealable plastic bag or shallow dish. Pour the marinade over, ensuring each piece is evenly coated. Cover and refrigerate for a minimum of 20 minutes, up to 4 hours.
03 - While the chicken is marinating, mix diced mangoes, chopped red onion, diced red bell pepper, seeded and chopped jalapeño, lime juice, and chopped cilantro in a medium bowl. Season with salt and pepper to taste. Gently toss and set aside.
04 - Preheat a grill or grill pan to medium-high heat.
05 - Remove the chicken from the marinade, discarding any excess. Grill each chicken breast for 6 to 7 minutes per side or until fully cooked and the internal temperature reaches 165°F (74°C).
06 - Transfer the grilled chicken to a plate and let it rest for 5 minutes to retain juices.
07 - Place each chicken breast on a plate and top generously with mango salsa. Garnish with fresh lime wedges and cilantro leaves.
