In a mixing bowl, combine olive oil, soy sauce, honey, minced garlic, black pepper, salt, paprika, and oregano. Mix well.

Add the chicken breasts to the marinade, ensuring they are fully coated. Cover and refrigerate for at least 30 minutes, or up to 4 hours.

Preheat the grill to medium-high heat.

Remove the chicken from the marinade and discard the marinade. Place the chicken on the grill.

Grill for about 6-7 minutes on each side, or until the internal temperature reaches 165°F (75°C).

Remove from the grill and let rest for 5 minutes before slicing.
