Best way to use spent grains for best flavor

Toast

I have about 2 pounds of different spent grains (english chocolate is what I have most of). What is the best way to incorporate them to get the best flavor in the resulting loaf? Do they really add flavor? They are dried. Grind?Cook?

Give me some ideas,please.

not starch or sugar, and I'm not sure that gluten is destroyed by the brewing process.  There just isn't much of any food left for the wee beasties to eat - quite unlike non gluten flours that have plenty of high quality food to eat but no gluten proteins.  Still, 10-20% of anything can usually be used in bread without much ill effect if it isn't diastatic malt or Portland cement:-)

It sounds like I won't be getting much difference in the flavor department but may be more of adding whole grain bits to the texture and for the eye. Especially the English Chocolate. That one smells of a rich cocoa flavor and may add some chocolate nuances. There was a lovely looking biscotti in the link dabrownman sent. Hmmm....

OR 

It might be time for a nice chewy, thickly-grained rye that will improve as it ages. Too bad I didn't plan that ahead a bit for New Years!

Well, they are dried and ready for whatever. Any additional ideas?
