For a crunchy texture, fry the mash/spent grains, add a little salt and pepper, and then add them to any salad instead of croutons!
I don't know how the beer will turn out (it's bubbling madly as I write this) but the salad dressing is delicious.
P.S. 11/1/2013 -- The beer is great, and it's almost gone. Time to make some more.
