If you haven't done this already; I can suggest a way to make "quick" meals from your stored grains (wheat).
Grind a few cups of wheat, and make up a batch of Waffles or Belgian Waffles, and slap 'em in the freezer.

Then you can toast up a few any time for a quick breakfast/meal.

Granted, it takes just a little time and effort to make up the batch of waffles. But, after that's done, they're really quick and handy from the freezer.
That (or something similar) can be a great way to use your stored grains.

You don't have to worry so much about long-term storage, if you're regularly using (and then replacing) your supplies.
