Place each chicken breast half between 2 sheets of heavy-duty plastic wrap; pound each breast half to 1/2-inch thickness using a meat mallet or heavy skillet. Sprinkle both sides of chicken with salt and pepper.
Heat oil in a large nonstick skillet over medium-high heat. Place flour in a shallow dish; dredge chicken in flour. Add chicken to pan; cook 3 minutes on each side or until lightly browned. Add wine; cook 1 minute. Add olives and the next 4 ingredients (through tomatoes); bring to a boil. Reduce heat, and simmer 8 minutes or until chicken is done. Sprinkle with basil.
