Can you live off $5/week?

This husband and wife team is trying to eat off $10 for two weeks.  They each have their own $10 and their own stash of food.

It's interesting because Frank and I were just talking about this on the way to work yesterday.  What would you eat or buy if you had limited funds but access to a kitchen? Here are some of the things that would be on my list:

• oatmeal
• lots of beans
• canned vegetables
• peanut butter
• whole wheat bread
• maybe some bananas
