In a medium bowl, whisk together olive oil, soy sauce, honey, minced garlic, lime juice, cumin, smoked paprika, salt, and black pepper to create the marinade.
Place chicken breasts in a resealable plastic bag or shallow dish. Pour the marinade over the chicken, ensuring it's fully coated. Seal and refrigerate for at least 30 minutes, or up to 4 hours for deeper flavor.
Preheat an outdoor grill or grill pan to medium-high heat. Lightly oil the grates to prevent sticking.
Remove chicken from the marinade and discard excess liquid. Grill chicken for 6–7 minutes per side, or until internal temperature reaches 165°F (74°C).
While chicken is resting, toss diced mango and pineapple chunks with a splash of lime juice to keep them fresh and vibrant.
Slice grilled chicken into strips and top each serving with fresh mango-pineapple mixture. Garnish with chopped cilantro if desired.
Notes
Garnish with fresh cilantro or parsley for added color and flavor.
