In a large bowl, combine the first six dry ingredients. Slowly add oil, broth and chicken, and mix well. On a lightly floured surface, roll the dough to a thickness of 1/8 inch then place it on a greased cookie sheet.
Bake until golden brown.
Cool then break into bite-size pieces. Place pieces in a bag with the brewer's yeast and shake to coat them. Store the leftovers in an airtight container in the refrigerator.
