01 - Combine olive oil, lemon juice, minced garlic, dried oregano, paprika, salt, and black pepper in a mixing bowl. Whisk thoroughly to emulsify.
02 - Arrange chicken breasts in a resealable bag or shallow dish. Pour marinade over the meat, seal, and refrigerate for a minimum of 30 minutes up to 2 hours for enhanced flavor infusion.
03 - Preheat grill or grill pan to medium-high heat and lightly oil the grates to prevent sticking.
04 - Remove chicken from marinade, allowing excess to drip off and discard. Grill chicken for 6 to 7 minutes per side, or until an internal temperature of 165°F (74°C) is reached and juices run clear.
05 - Transfer chicken to a plate and let rest for 5 minutes before slicing. Garnish with chopped parsley and serve with lemon wedges if desired.
