I finally found (at Target!) one of the few Campbell's soups that is gluten-free: Chicken Broccoli Cheese (an potato). I was curious about the flavor and texture and can finally report on it.
It's a bit light for a meal. I found it flavorful enough for something out of a can. I think it would be perfect tossed with some cooked gf noodles (penne, linguini, or spaghetti) along with two cooked cans of the soup, perhaps with some gf biscuits. Nevermind the potatoes in it, it's not chunky enough that it would be noticable. It serves more like a thick sauce than a chunky soup.
It will be a repeat purchase to stock in my pantry, but it needs something more with it. I hear a caserole waiting to be improved with this addition....let me know if you discover it's perfect recipe/ dinner mate.
