Yeah, I really liked the idea this thread as well, but I can give a suggestion or two. I think that a lot of people out there think that Whole Foods is an expensive grocery store, but I swear by their bulk food bins. I'm on a pretty tight budget myself, so I really search for the deals. I'm not sure that all of the stores have the same inventory, of course, but I assume that they are at least similar. The lentils and quinoa are great price and go a long way. They also have a dried bean mix that I use for soups, it's about $5.99 a pound, when I buy half a pound and mix it with wild rice at about $4.00 a pound it lasts me for quite awhile. I guess that I gave a lot of soup suggestions, but if you don't get sick of soup these are pretty economical choices.
I hope that more people will respond to this, I'm sure that a lot of us are trying to eat well and stick to a budget, it's not always easy, so we need to help each other out in that area as well.
