To make the starter: Mix the flour, salt, yeast, and water. It will be very dry; If it doesn't come together, add a bit more water. Cover and let it rest at room temperature, it will become bubbly. To make the dough: Combine the risen starter, with the water, salt, flour, and yeast. Knead, (you may use a mixer or bread machine on the dough cycle,) to make a smooth dough. Place the dough in a lightly greased bowl, cover and let rise for 1 1/2 to 2 hours, until it is nearly doubled. Pat and stretch the dough into a 9" x 12" rectangle. Spritz with water and sprinkle with cheese. Starting with the long side, roll into a log, pinching the seam to seal. Place the log, seam-side down, on a lightly floured or lightly-oiled surface. Cover and let rise for 1 to 1 1/2 hours, until it is puffy, but not doubled. Preheat the oven to 425 degrees. Cut the log into 4 crosswise slices, for mini-breads; or simply cut in half for 2 loaves. Place them on 1 (for 2 loaves) or 2 (for mini-loaves), lightly greased, silpat, or parchment lined baking sheets, cut side up. Spritz with warm water. Bake for 20 minutes (for the mini-loaves) or 35 minutes (for the full sized loaves), or until the cheese is melted and the loaves are very deep golden brown. Remove from the oven and serve warm.
