I think it's Country Beans
that has soup recipes that use white bean flour. You run dry beans through your grain mill and get bean flour. Mix that w/ boiling water and you can add cooked chicken for cream of chicken soup, or sauteed mushrooms for cream of mushroom soup, same for celery, etc. I can't recall what, if any, seasonings she adds, and I'd look it up to tell you amounts and seasoning info, but my copy is in storage. I can't wait to live w/ all my books again!
I bet you could figure it out easily by experimenting.
I think you're looking for a brand of prepared canned soup that's healthy, and I think Hains is organic, but don't know if they sell soups. I found Amy's Kitchen in a quick search, but it's pricey. This is just one site, I'm sure you can find others. Of course,if you can get it by the case, the price per can should be lower. Amy's Kitchen cream of mushroom soup
If you have a grain mill, the method above may work for you and it's pretty cheap! Country Beans
