In a small bowl, whisk together honey, lime juice, lime zest, olive oil, garlic, cumin, smoked paprika, salt, and black pepper.
Place the chicken breasts in a shallow dish or resealable bag.
Pour the marinade over the chicken and coat thoroughly.
Cover and refrigerate for at least 30 minutes or up to 12 hours.
While the chicken marinates, prepare the salsa by combining diced mango, red onion, jalapeño, and cilantro in a medium bowl.
Add lime juice and season with salt and pepper.
Stir gently and allow the salsa to rest for 10–15 minutes.
Heat a grill pan, skillet, or outdoor grill over medium-high heat.
Remove the chicken from the marinade and cook for 5–7 minutes per side, or until the internal temperature reaches 165°F (74°C).
Transfer the chicken to a plate and let it rest for 5 minutes.
Slice the Honey Lime Chicken With Mango Salsa and top generously with the prepared mango salsa.
Serve immediately with rice, quinoa, salad greens, or warm tortillas.
