I don't remember where I found this recipe, maybe the Atkins site, but it is so good!

Ingredients


2 cups cauliflower, finely chopped
1 tablespoon sour cream, or more to taste
1 tablespoon butter
salt and pepper to taste


Directions
1 Steam or microwave cauliflower until very soft.
2 Put cauliflower in blender or food processor with butter and sour cream, blend.
3 Add salt and pepper to taste. Serve hot.
Editor's Notes:

Frozen cauliflower works very well.

Grated cheese, minced chives and/or parsley are nice variations to add. Hand mix these in after blending the cauliflower.
