I made a couple of loaves of this yesterday, this time adding oats, as I found a can of steel-cut oats in the pantry.

I used about a quarter cup of oats for two loaves, pouring boiling water over them and letting them soak for about two hours before mixing the dough.  The results tasted good, but the oats seemed to add more to the texture than to the flavor,  

I note, though, that the results passed the girlfriend test with flying colors.
