Soup for a cold cold day

When you grocery shop, do you ever find yourself buying an item that you have no idea how you will use it or when? It looks so fresh and is likely a good price so into the basket it goes! This week it was a cauliflower. When I got home it occurred to me that I had a substantial piece of wonderful Black River 2 yr old cheddar cheese that needed to be used within the next couple of days....bingo! ....Cauliflower Cheese Soup. I use a recipe from the original Moosewood vegetarian cookbook that is delicious. Starting off with about 4 cups of water, 2 cups of potatoes, some garlic, a large onion, 2 cups of carrots and 2 1/2 cups of cauliflower you simmer this until cooked; then blend it. Add about 3/4 cup milk, 1 1/2 cups shredded cheese, 1/2 tsp dry mustard about 1/4 tsp dried dill weed, 1 1/2 cups more cauliflower that has been sauteed in just a bit of butter. Just before serving add 3/4 cup or so of plain yogurt. A steaming wonderful bowl of healthy soup for a winters day is yours for the taking....and as this makes a large soup pot there is plenty to share or save for another day or two.
