2. Heat 1 tablespoon olive oil in a large heavy casserole over medium-high heat. Add the chicken in a single layer with space between each piece, season with salt and pepper and cook until lightly golden on each side, 10 minutes total.
3. Remove the chicken from the pan and pour off the excess fat. Increase the heat to high, add the wine to the pan and reduce by approximately half, about 10 minutes. Add the drumsticks and thighs to the pan along with the garlic, chicken stock, tomatoes and tomato paste. Bring to a boil, reduce the heat to low and simmer 5 minutes. Add the breasts and continue to cook covered until the juices from the chicken are clear when pierced with a knife, 20 to 25 minutes.
4. Remove the chicken from the pan with tongs and set aside, covered with foil to keep warm. Adjust the heat to high, add the olives and capers and simmer until the liquid reduces by half and thickens, 10 to 15 minutes.
5. To serve, heat the sauce over medium-high heat until it is simmering. Add the chicken and heat thoroughly, 2 to 3 minutes. Place the chicken on a platter and drizzle the sauce over the top. Garnish with parsley.
