In large bowl, combine 2 cups unbleached flour with yeast and salt. Heat water, cottage cheese, butter and honey until very warm (120-130). Add warm liquid and eggs to flour mixture. Mix well. Add whole wheat flour, oats, and nuts. Stir in remaining unbleached flour (add more if necessary) and knead until smooth and elastic. Let rise until doubled. Punch down and place in two greased 5 1/4x9 1/4x3 inch pans. Let rise about 1 hour. Bake at 350 for 35-40 minutes. Remove from pans to cooling rack. Brush tops with butter.
