My daughter and I just sampled some soups from Kettle Cuisine that just showed up in our grocery store's gluten-free freezer section. My daughter tried the "Chicken Soup with Rice Noodles" and I tried the "Angus Beef Steak Chili with Beans." We give those two varieties two thumbs up (I did get a chance to sample the chicken soup, but my daughter didn't want to try the chili, since she's not a fan of beans).
Kettle Cuisine has a few other varieties of soup that I'm sure are equally as delicious. I just wanted to be sure to share this brand, since we found them to be quite yummy. The portion sizes are probably just the right size for a lunch and can be microwaved right out of the box in the bowl it comes in. It was probably a bit small of a portion to be eaten alone as a dinner meal, so perhaps serve with a gluten-free sandwich.
