My husband was recently diagnosed with a gluten allergy and he absolutely HATES soup. However he gobbled this up, ranting and raving on how good it was.
Also -- if you have picky eaters -- this is a perfect soup since you can pick and choose what goes in your bowl.
My favorite part was how healthy it is. You can taste the freshness (since you don't cook the nutrients out of the vegetables). Also, this would be so simple to convert into a vegetarian/vegan dish.
The only thing I would do differently is make more of the stock!
