Rachel of Tangerine's Kitchen is hosting the bbd this month and she chose Multigrain Breads.
I tried the 'Sourdough Wheat Bread with Seeds' from Rose Levy Beranbaum's 'The Bread Bible' but with a multigrain flour mix that contains wheat, barley, oats, rice, rye and corn. This bread is wonderful and adding all these cereals even improves it !!

The recipe is very long and I can't copy it right now but PLEASE let me know if you are interested in it !!
