I took TwistTieCollector's advice earlier this summer and ordered some of those eggs from the egg store.  First of all, they are excellent!  I mix them with some dried diced onions, some Hormel pre-cooked bacon, and fry them.  They are almost indistinguisable from real eggs.  Really.

I followed the instructions about mixing with the fork, but found it was unnecessary as I use a small whisk.  2 tbsp of egg powder to 3 tbsp of water (per egg) and mix it all up with the whisk.  I've eaten this probably a dozen times this spring/summer and it is my favorite trail breakfast.
