new things, flax seeds and wheat bran

Options
At least I think that is what I bought. It was in the bulk food section at my grocery store I know the flax seeds are whole so I need to grind them and I think it was wheat bran or wheat germ. It is really light and fluffy. I added the wheat bran to my rolled oats when I was cooking it last night was pretty good. And added it to my protein shake. Any other ideas of things I can do with this? I also got this weird idea of mixing the two to make a flour and making some kind of healthy cookie for my kids. It was actually REALLY cheap for both the flax seeds and the wheat bran. I was shocked. I also have a bread maker so I could start making breads?
