Dave T..the pea soup blocks can be had at Repo Rations Inc
http://reprorations.com/
they sell it as part of the WW One Germany iron ration but have a small supply without the army wrapper.it's Knorr brand soup called Erbswurst and not sold in the US as far as i know.i have cooked it up as a lunch on canoe trips when i wanted a good filling meal on a cold day.one block of that stuff will make a heavy,thick and good tasting meal.as a survival ration i plan on using it as a base for any wild game i can come up with,fish,turtles,frogs..or that rat stew i mention in some of my posts------

i believe there's a similar thing sold stateside in "higher end" grocers like Publix. same brand even(i have a few packs of their hollandaise sauce in the cabinet). it comes in powdered form in flat packets. i've never tried the pea soup, but i'll be doing so soon.
