Start by marinating the chicken. In a mixing bowl, whisk together olive oil, honey, chili powder, smoked paprika, salt, black pepper, minced garlic, and lime juice.
Immerse the chicken breasts into this spicy marinade, ensuring every part is well-coated. Allow it to sit for at least 30 minutes; the longer, the better!
Preheat your grill to medium-high heat.
Once ready, place the chicken on the grill. Cook each side for about 7-9 minutes or until fully cooked through.
Halfway through grilling the chicken, arrange the mango slices on the grill. These need just about 2-3 minutes on each side to get those beautiful grill marks.
Remove the Spicy Grilled Chicken and Mango from the grill and let them rest for a few minutes. This lets the juices redistribute, ensuring every bite is juicy.
