Woogie is bang on!
It is a wonderful idea living on a dollar a day, but you obviously need the advanced forsight or income to buy in bulk and to stock a pantry with all the basics. Now, if the government helped all the poor by giving them vouchers for the staple products...
In saying that...it is very possible to live and eat well on far less than most of us are spending. We need to go back to basics in this economy and live like our grandparents and their parents lived! They all managed to eat well and be merry on considerably less!

So stock those pantries on staple products and find frugal minded recipes...bon appetit!
