I used an onion instead of the leeks, and added a finely chopped stalk of celery. I didn't pay attention to the directions and added the mushroom soup with the rest of the ingredients - still tasted great. Even better the next day.
A meal that is both easy to prepare and tasty. I used 1/2 cup of a brown rice and wild rice blend that I get at Costco and 1/2 cup white rice as I didn't have enough of the brown/wild blend to make a full cup. This is more like a thick soup than a stew - I think you could use either a fork or a spoon to eat it!
