Actually - Pot Noodles are excellent for climbing mountains in the Andes. They weigh very little, just need hot water to turn them into something edible, and when you've climbed a few thousand feet to get to your bivouac, you're hungry enough for them to be delicious. There's even enough calories in to get you up the rest of the mountain. I would however never put them near my mouth in any other circumstance!
Cheers
