I start with 94 (or maybe 96) percent lean, stir well while cooking so no big chunks, drain and press with paper towel, and put in dehydrator for 12 hours.  I don't rinse.  Looks like Grape Nuts to me - but that seems close to coffee grounds and gravel.  Tasted great.  I used in spaghetti (all dehydrated ingredients) and with stroganoff pasta side. A 1/4 pound single serving dehydrated weighs nearly nothing.

Looking forward to chicken - was thinking I'd grill boneless and skinless breasts but the roasted chicken sounds like a winner.
