Add the chicken breasts to the marinade and coat them well.
Cover and refrigerate for at least 30 minutes, or up to 8 hours for even more flavor.
Preheat your grill to medium-high heat.
Lightly oil the grill grates to prevent sticking.
Remove the chicken from the marinade and let any excess drip off.
Grill for 5 to 7 minutes per side, depending on thickness, until the internal temperature reaches 165°F (74°C).
Transfer the chicken to a plate and let it rest for 5 minutes before slicing.
Sprinkle with fresh parsley and serve warm.
