01 - Set the oven broiler to high. Line a baking sheet with aluminum foil and lightly brush the surface with olive oil to prevent sticking.
02 - Arrange the chicken breasts on the prepared baking sheet. Drizzle with olive oil, then sprinkle evenly with dried oregano, salt, and freshly ground black pepper.
03 - In a medium mixing bowl, combine the drained and quartered artichoke hearts, crumbled feta cheese, sliced sun-dried tomatoes, minced garlic, fresh lemon juice, and chopped parsley. Toss gently until all ingredients are evenly distributed.
04 - Spoon the artichoke-feta mixture evenly over each seasoned chicken breast, pressing lightly so the topping adheres.
05 - Place the baking sheet about 6 inches from the broiler heat source. Broil for 16 to 18 minutes, until the chicken reaches an internal temperature of 165°F and the topping turns golden brown.
06 - Remove from the oven and let the chicken rest for 2 to 3 minutes to allow juices to redistribute. Garnish with additional fresh parsley before serving.
