01 - Preheat the broiler to high heat. Position oven rack approximately 6 inches from the heating element. Line a baking sheet with aluminum foil and lightly coat with oil.
02 - Combine olive oil, lemon juice, minced garlic, dried oregano, salt, and black pepper in a small mixing bowl. Whisk thoroughly until fully emulsified.
03 - Arrange chicken breasts on the prepared baking sheet. Brush both sides of each piece generously with the marinade mixture.
04 - Place under the broiler and cook for 7 to 8 minutes per side. Flip carefully using tongs halfway through. Continue until internal temperature reaches 165°F and exterior develops golden coloration.
05 - Remove the partially cooked chicken from the oven. Distribute quartered artichoke hearts, sliced sun-dried tomatoes, and crumbled feta cheese evenly across each breast.
06 - Return to the broiler for an additional 2 to 3 minutes. Watch closely until feta cheese becomes lightly golden and bubbly.
07 - Remove from oven. Sprinkle with fresh chopped parsley and basil. Transfer to serving plates and present immediately while hot.
