Prepare as usual for any yeast bread except for the cornmeal. Let rise until doubled and punch down. Form into 4 long skinny loaves by rolling a flat surface. Sprinkle baking pans with cornmeal and place 2 loaves on each sheet, spray lightly with a water mister, cover and let rise for 45 minutes. Brush loaves with an egg wash, and slice each bread with 3 diagonal cuts with a sharp knife. Place in a 450 degree oven and bake for 15 minutes. Spray breads with a water mist, lower oven temperature to 375, and bake again for another 15 minutes. Spray loaves for the last time, and finish baking for 10-15 minutes or until browned. Remove and cool on wire racks.
