Be-Well Meals
Be-Well supply freeze-dried meals and other foodstuffs to a number of major expeditions. Their products are used and endorsed by the explorer Sir Ranulph Fiennes, perhaps most famous for his incredible journeys in Antarctica.
Be-Well Pack 'n' Go meals are all of the "cook in the pouch" type: simply add boiling water up to the indicated fill line, close the pouch and wait for 8 minutes. The prices are very competitive: ideal if your budget is stretched!
