Combine the first 4 ingredients in a food processor and pulse until mixture resembles coarse crumbs.  Add red pepper flakes and half and half and process until dough forms a ball, about 10 seconds.

 

On a well floured surface, roll into a rectangle, about 1/8 inch thick.  Using a pizza wheel or a big knife, trim the edges a bit to even them up and then cut the dough into straws about 1/4 inch wide.  Place on an ungreased baking sheet (I like to use parchment paper).

 

Bake at 350 degrees for about 10 minutes until ends are just slightly browned.  Cool on baking sheet on a wire rack.
