Pat the dough into 2 loaves approximately 1-inch high and 2-inches wide. Bake at 325F for 25 minutes or until golden brown. Remove from oven and slide off the baking pan onto a cutting board. Cut loaves into 1/2-inch thick slices and place them back onto the baking pan laying on their side. Return baking pan to the oven at 400 degrees, and bake another 10 minutes or until crisp.
