So for lightweight trips I tend bring several types of meals that use pasta noodles. I always assumed that if weight and space are priorities, that angel hair pasta was the way to go since it packs very dense and can cook quickly with minimum fuel usage. The only downside is that the noodles are long and somewhat awkward to pack.
I've also found meals involving cuscus and quinua cook fairly quickly and fit into a small space. Anyone else have any preferred meals when space is a premium?
