I've just posted two short videos about military meals in cans which are used in field kitchen in the Polish army
The dishes are new and some of them really interesting - 2 soups - Ukrainian borshtch and onion soup with meat, one main dish - sausage with cabbage and one cold meal - browned minced meal in jelly (man, this was excellent).
As a bonus I checked also small can with headcheese called sapper headcheese - it this case one can fail only once

Videos are in Polish, but have English subtitles. If somebody is interested in these cans I can get it.
