I like to have instant oatmeal packets and instant lipton soup packets - the soup packets serve the same purpose as the ramen but they're smaller to pack. Salty noodly broth, mmm. And oatmeal packets for the morning.
When I was a college ski bum I'd carry hot cocoa and oatmeal packets in my jacket, then take a cup from the cafeteria and ask for, or find hot water. That was lunch plus maybe a granola bar and of course, a bag of jelly beans or skittles... so good frozen!
