I have found that pureed vegetables are great as a soup and also as an addition to anything that you bake that might need liquid such as meatloaf or even quiche. Our favourite soup this winter was pureed broccoli and potato. Sometimes We would dress it up sometimes with some cheese but normally we had it without anything other than some vegetable boullion to make it less thick and add herb flavors. It’s important to make it about the vegetable and not the potato so you should limit how much potato you use. Other root vegetables such as carrots or sweet potatoes don’t need a white potato to make it into a thick soup. Our grandchildren like carrot soup and we like sweet potato soup with spices. And if you want to really dress it up, you can always add just a bit of melted butter or even olive oil with some tarragon or other fresh herbs. The great thing about these soups is that they have a fabulous mouth feel and they really fill you up!
