In a blender or processor whirl chicken, egg and broth until smooth. Scrape into bowl. Add cornmeal and 1/2 cup flour, stir until moistened. Cover dough and refrigerate at least 2 hrs. Then roll out 1/4 in thick on lightly floured board. Cut into 1/2 in squares or triangles. Scatter on 3 greased 12 x 15 baking sheets. Bake at 350 until golden (about 15 min.) Remove from oven, stir in pans and let cool. Refrigerate airtight up to 2 weeks, freeze for longer storage. Makes about 3 cups.
