I also eat a lot of grains, including a lot of "natural" rice.   I'm going to try your recipe this weekend.  I've never dehydrated rice before, so it should be interesting.

Have you ever tried quinoa (pronounce keenwa)?  Its a very nutritious seed from S. America originally,  it cooks relatively fast (15 minutes) and to my taste, is delicious.  It has many of the essential amino acids so it's better nutritionally than most grains.

I've dehydrated beans before and they work great.  For most beans all you need is water, cold or hot.  My favorite is Anasazi beans, as they have less complex carbohydrates fats and are more easily digested than pinto.

Thanks for the idea.
