Combine flours in large bowl and mix in salt. Dissolve yeast in 1/2 cup warm water. Add olive oil. Make well in center of flour and add yeast mixture and Starter. Mix well, adding just enough warm water to incorporate all flour. If dough is not stiff enough it will flatten. Mix 4 minutes, then cover bowl, put in warm place and let rise 2 hours. Punch dough down 2 to 3 minutes, roll into 6-inch ball. Lightly grease Dutch oven and sprinkle with cornmeal. Gently place ball of dough in Dutch oven. Let rise about 1 hour, or until doubled. With sharp razor, gently slash top of loaf with X, making shallow incisions so dough wont sink. Cover Dutch oven and bake at 500° 20 minutes. Turn oven down to 300° and bake 35 to 40 minutes more, or until loaf is golden and crusty. Turn bread out of Dutch oven and cool on rack. Makes 1 loaf, or about 8 servings. Each serving contains about: 299 calories; 462 mg sodium; 2 mg cholesterol; 5 grams fat; 54 grams carbohydrates; 11 grams protein; 1.02 grams fiber. Note: If you do not have Dutch oven, place bread on cornmeal sprinkled baking sheet to rise. Place baking sheet on center shelf in 500° oven. Place pan filled with hot water on oven floor. Bake 20 minutes, remove water, turn oven down to 300° and bake 35 to 40 minutes more or until loaf is golden and crusty. Remove from oven and let bread cool on baking sheet. TIP: A Dutch oven is wonderful for baking bread, as it creates an oven within the oven, which provides even heat for the loaf and makes the crust crisper. Good flour is important when baking bread, as is good water; if you have bottled water, use it.
