01 - In a mixing bowl, whisk together olive oil, fresh lemon juice, minced garlic, dried oregano, paprika, salt, and black pepper until fully emulsified.
02 - Arrange chicken breasts in a resealable bag or shallow dish. Pour marinade over the chicken, ensuring each piece is well coated. Seal and refrigerate for a minimum of 30 minutes or up to 2 hours for enhanced flavor.
03 - Set grill or grill pan to medium-high heat. Lightly oil the grill grates to prevent sticking.
04 - Remove chicken breasts from marinade and discard any remaining liquid. Grill chicken for 6 to 7 minutes per side, turning once, until fully cooked with an internal temperature of 165°F and juices running clear.
05 - Transfer chicken to a cutting board and let rest for 5 minutes before slicing. Garnish with chopped parsley and serve with lemon wedges as desired.
