It's easy to keep the Greek theme going by starting with stuffed grape leaves, widely available at supermarkets. Accompany the chicken with orzo and steamed baby carrots with mint. Finish with purchased cheesecake.
Heat oil in heavy large skillet over medium-high heat. Sprinkle chicken with salt and pepper. Add to skillet and sauté chicken until browned on all sides, about 10 minutes. Add 2 tablespoons reserved marinade, broth, lemon juice, peel, and crushed pepper. Reduce heat to low, cover and simmer until chicken is almost cooked through, about 10 minutes. Uncover; stir in artichokes and 2 tablespoons oregano. Simmer until liquid is slightly reduced and chicken is cooked through, about 5 minutes. Stir in 1 tablespoon oregano. Season with salt and pepper; serve.
