i am pretty sure you can pop all of those in the freezer to give yourself a little more time to use them up.
the brans you could add to granola. i'm pretty sure you could also mix them into oatmeal as well, but i don't eat oatmeal so you might want to run that by someone who has actually tried it.
if you wanted to make your own bread or pizza dough, you could add a bit of each in. i used to do this all the time with wheat bran and millet and the basic puck pizza dough recipe. i'd leave out just a bit of flour and replace it with a little less bran and millet [so that the wet/dry balance would work out].
-google first. ask questions later.
