I brew only extract recipes so the amount of spent grains are not too much trouble to deal with. I dry these in the oven and then turn into spent grain flour using a coffee grinder. This makes a nice substitute for regular flour (usually a tablespoon or so for a loaf of bread or most of my recipes). It gives a nice added flavor and color without being overly dense and heavy if excessive spent grain flour were to be used. I add to breakfast smoothies, pizza dough, honemade granola bars and granola cereal, pancakes, chocolate chip oatmeal raisin cookies, and chocolate cake to name several good uses. A great way to recycle instead of tossing it in the dumpster and letting it go to waste.
