I read this last week: http://www.msnbc.msn.com/id/36507576...and_nutrition/

Interesting that "ethnic" cooking turned out to be the cheapest. I know I cook about twice a week and just eat leftovers, but I know several people that refuse to eat them. I don't know how you can be so wasteful. Personally, I know I could spend less, but I have no problem spending more for something I know is high quality, i.e. organic or grass-fed.
