Here's what I lived on for a few months in college. It doesn't get any cheaper or easier than this.

1 package ramen noodles
1 kraft single (or store brand equivalent american cheese)

Cook noodles, drain, put in big plastic cup, add torn up american cheese slice and 1/2 of the seasoning pack from the ramen. Stir. Ta-da! Instant really poor man's macaroni and cheese!
