MSG-free Cream of Mushroom soup?

[kittykat2481]

I'm so excited for Thanksgiving, and can't wait to make my famous green bean casserole, but every cream of mushroom soup I can find has MSG in it, and now that DS is here, I'm much more conscious of what I use in my cooking. I'd love to make a casserole that is better for him to eat, since I really don't want him to miss out on this tradition, but I'd rather him not have MSG either. Thanks!
