Ramen noodles. Spurge and get the $1 package instead of the 24 pack/$2.89.
Add in your favorite dried vegetables, meat and seafood. Dried shrimp and stretched squid are good. I knew some guys who would buy the cheap ramen and bring their own dried 'bulk' vegetables from some guys drier.
Try Picante Lime Shrimp with a couple tablespoons of jarred "Patek's Hot Lime Relish"(get the 'hot', not reg) sold in Indian food stores. Not dried but I don't think it will go bad in a small gladware mini-tub. SO good.
