Put a large pot of water on the stove to boil. Cut the cauliflower into small pieces. When the water is boiling, put the cauliflower in the water and boil for 15 minutes or until a fork easily pierces the cauliflower.
Drain, put in a large bowl, and either blend with a stick blender or a potato masher. Add the remaining ingredients and mix. Taste and add more salt if necessary. Serve.
