How to Make It
Place each chicken breast half between 2 sheets of heavy-duty plastic wrap; pound each piece to 1/2-inch thickness using a meat mallet or small heavy skillet. Sprinkle both sides of chicken evenly with salt and pepper; dredge chicken in flour.
Heat oil and butter in a large nonstick skillet over medium-high heat; cook for 1 minute or until lightly browned, stirring occasionally. Add chicken to pan; cook 4 minutes on each side or until done. Remove chicken; slice thinly, and keep warm. Add wine and juice to pan; cook until reduced to 1/2 cup (about 4 minutes). Serve sauce over chicken.
