Oh hell yeah! In the 60’s before freeze dried meals became available my Boy Scout troop carried these both hiking and canoe tripping. My favorite was Veg-a-Rice, although they all tasted pretty much the same. We also had (freeze)? dried sausage patties in a can. When you opened the can there was a sucking sound, so i guess they were vacuum sealed. You simply poured boiling water into the can, to the top, and the two patties re-hydrated and were hot. Eat them too soon and they were a bit dry. Not bad tasting though! I don’t recall who made them… maybe Armour meats??Worst? Anybody remember the Siedel (sp?) packets?
