I bought some of these a while back with the intention of trying them out as cycle camping food, but there's been no cycle camping.
I have however been using them when I've needed lightweight foodstuffs on other trips
or just when I'm feeling hungry/lazy at home!
Dehydrated rice - you pour some boiled water into the pouch with the flavour sachet, zip-lok it and come back several minutes later. It's not a huge portion - probably not up to evening appetites after a day or touring - but it might be a useful fall-back if you're somewhere remote or if you're doing something audaxy and just have a small stove for heating water (80g and you don't even need to pack a spork!).
Anyway, thought it might be a useful find to share. I get mine from the international bit of a nearby large Tesco.
