Lentil Bread

In a saucepan, combine the lentils, water, onion and garlic; bring to a boil. Reduce heat; cover and simmer for 30 minutes or until lentils are tender. Cool slightly. Transfer mixture to a blender or food processor; cover and process until smooth. Cool to 110°-115°., In a large bowl, dissolve yeast in warm water. Add the milk, lentil mixture, oil, sugar, Parmesan, salt, whole wheat flour and 3 cups bread flour. Beat until smooth. Stir in enough remaining bread flour to form a soft dough. Turn onto a floured surface; knead until smooth and elastic, about 6-8 minutes. Place in a greased bowl, turning once to grease top. Cover and let rise in a warm place until doubled, about 1 hour., Punch dough down. Turn onto a lightly floured surface. Divide into thirds; shape into loaves. Place in three greased 9x5-in. loaf pans. Cover and let rise until doubled, about 30 minutes. Bake at 375° for 35-45 minutes or until golden brown. Remove from pans to wire racks to cool.
