How to Make It
Place each chicken breast half between 2 sheets of heavy-duty plastic wrap; pound to 1/4-inch thickness using a meat mallet or small heavy skillet. Combine chicken seasoning, salt, and pepper; sprinkle over both sides of chicken. Sprinkle sage evenly onto underside of each breast half; top each with 1 prosciutto slice. Place flour in a shallow dish; carefully dredge chicken in flour.
Heat oil in a large nonstick skillet over medium-high heat. Arrange chicken, prosciutto side up, in pan; cook for 3 minutes. Carefully turn over, and cook for 3 minutes or until done. Add wine and broth to pan; simmer 5 minutes or until reduced to about 1/4 cup. Serve sauce over chicken.
