Heat oven to 400 degrees. In a medium bowl, combine all ingredients except butter, eggs, and half-and-half. Cut in butter until crumbly. Stir in eggs and half-and-half just until moistened. Turn dough onto lightly floured surface; knead until smooth (1 minute). Divide dough in half; roll each half into 8" circle. Cut each circle into 8 pie-shaped wedges. Place 1" apart on cookie sheets. Bake for 15 to 20 minutes or until lightly browned.
