If you can only spare ten dollars every week to feed yourself, here are some  suggestions:

     1. Ramen noodles - you can get six packs of noodles for one dollar. 
     2. Hot dogs - you can usually get a pack of hot dogs for one dollar.
     3. Eggs - unless you just love eggs, a dozen should do for the week.
     4. Bread - one loaf of bread will feed you nicely for a week.
     5. Water - you can't afford bottled but tap will do.
