1. Combine breadcrumbs, 1/4 cup capers, 1 tablespoon Simple Preserved Lemons, 6 olives, and garlic in a food processor or blender, and pulse 10 times or until the mixture is coarsely chopped.
2. Place each breast half between 2 sheets of heavy-duty plastic wrap; pound to 1/4-inch thickness using a meat mallet or small heavy skillet. Divide breadcrumb mixture into 4 equal portions; spread 1 portion on each breast half, leaving a 1/4-inch border around outside edges. Roll up each breast half, jelly-roll fashion, starting with short side. Secure with wooden picks or twine.
3. Heat oil in a large nonstick skillet over medium-high heat. Add chicken to pan; cook 6 minutes, browning on all sides. Remove chicken from pan; keep warm. Add onion to pan; sauté 2 minutes or until browned. Add wine; cook until reduced to 1/4 cup (about 1 minute), stirring often. Add remaining 2 tablespoons capers, 1 cup water, broth, juice, raisins, and turmeric. Quarter the remaining 6 olives. Add to pan; bring to a boil. Add chicken to pan; cover, reduce heat, and simmer 20 minutes, turning chicken after 10 minutes. Serve chicken with sauce.
