Favourite homemade soup recipes using blender ......?

I really like potatoes, yellow onions and cauliflower - cooked until soft in chicken stock (boullion cubes are fine) and then blended. I make this in a medium-thick version, then add stuff based on my mood: cooked chicken and mild chiles is a favorite addition. This soup keeps well and you can also season with ground cumin to make it a bit MIddle Eastern.
