I made a cauliflower blue cheese soup for dinner as well.
This was my first time trying it and it was really good. I looked at some recipes on the internet and this is what I came up with.

Saute veggies in butter until tender then add:
1 cauliflower chopped up cook a couple of minutes then add:
21/2c. chicken broth
1 bay leaf
1/4t. white pepper

Puree in blender or with immersion blender stick.
Then add 3/4c. milk
1/4c. cream stir until all blended then add
1/4c -1/2c. gorgonzola cheese until melted.
