In a blender or food processor, combine pineapple, cilantro, lime juice, olive oil, honey, garlic powder, cumin, salt, and pepper. Blend until smooth.

Reserve 1/4 cup of the marinade for later use and pour the rest over the chicken breasts. Let the chicken marinate in the fridge for at least 30 minutes (or up to 2 hours for more flavor).

Preheat the grill to medium-high heat.

Remove chicken from the marinade and grill for 5–7 minutes per side, or until fully cooked and internal temperature reaches 165°F (75°C).

Once grilled, drizzle the reserved marinade over the chicken and serve with lime wedges.
