In a large bowl, combine the first 7 ingredients; cut in butter until crumbly. Stir in cheese. Gradually add water and vinegar, tossing with a fork until dough forms a ball. Wrap securely in waxed paper and refrigerate for 1 hour or until firm.
Divide into 6 portions. On a lightly floured surface, roll each portion into an 8-in. circle. Cut into 8 wedges and place on greased baking sheets.
Bake at 375° for 17-20 minutes or until edges are lightly browned. Cool on wire racks. Store in an airtight container.
