Place chicken between 2 sheets of heavy-duty plastic wrap, and flatten to a 1/4-inch thickness using a meat mallet or rolling pin.
Spread cheese evenly over 1 side of each chicken breast. Fold short ends of each chicken breast over center, covering cheese, and secure with wooden picks.
Whisk together egg whites and buttermilk in a small bowl. Combine breadcrumbs and next 3 ingredients in a shallow dish. Dip chicken in egg white mixture, and dredge in breadcrumb mixture.
Cook chicken breasts in hot oil in a large nonstick skillet 4 to 5 minutes on each side or until chicken breasts are browned. Place chicken on a wire rack, and place the wire rack in a jelly-roll pan.
Bake at 400° for 20 minutes or until a meat thermometer inserted into the thickest portion of chicken breast registers 170°.
