I use the term "food" some may disagree, but if you're traveling light and want something quick and easy and light to carry Aldi are doing a range of Asia noodles for 25 pence a pack and unlike certain big name noodles they actualy have some flavour, they say add 400 ml of boiling water and stand but I find that 350 ml and simmer works best, obviously not a staple diet for a trip but quick and easy to warm you up in a bivy in the rain.
