Cut cauliflower into bite size pieces and place on a lg sheet of heavy duty aluminum foil that has been sprayed with cooking spray, add garlic, salt and pepper. Wrap tightly in foil and roast for 30 min on 375. I roast first because the end result is much more flavorful.

Remove from oven and steam for 10 minutes. It should break easily when pierced with a fork.

Add cauliflower and remaining ingredients to a food processor or blender and blend to mashed potato consistency. Done!!!
