Stir all of the ingredients together by hand in a large mixing bowl (or in the bowl of a stand mixer fitted with a paddle) just until combined. The dough will be shaggy and very sticky.
Spray a piece of plastic wrap with non-stick cooking spray and lay it loosely over the mixing bowl. Let the dough rise in a warm, draft-free place for about an hour or until it looks bubbly and puffy.
Spray 3 or 4 standard loaf pans (8.5" or 9.5" x 4") with non-stick cooking spray and sprinkle in a fistful of cornmeal. Tilt the pans, tapping gently, until the interiors are coated with a thin layer of cornmeal. Tap out any excess cornmeal.
Spray your hands with non-stick cooking spray and use them to divide the dough evenly between the pans. The pans should be no more than halfway full. If you need to, spray and cornmeal an additional loaf pan for any excess.
Spray more pieces of plastic wrap with non-stick cooking spray and lay them loosely over each loaf pan. Let rise in a warm, draft-free place until the dough looks bubbly and puffy again, and has risen with the top of the dough dome just peeking above the edge of the pan.
While the dough is rising, preheat the oven to 350°F.
