Cut one head of cauliflower into chunks.  Pulse in food processor until rice-like.  Melt 1 T butter in pan.  Add cauliflower and cook over medium heat for about 5-7 minutes.

Wash and cut cauliflower, boil for 5-10 minutes (until fork tender). Remove cauliflower with a slotted spoon and transfer to food processor and blend with butter, salt, and pepper until smooth.  If liquid is needed to make creamier, feel free to use a little milk or water from boiling.
