Place cauliflower and leeks in pot with about 3” water (use a 1 1/2 quart pot); bring to boil;
reduce heat and simmer to steam cauliflower until very tender. Drain thoroughly.*
* be sure all water is out so that your mock mashed potatoes are not watery
Use either a handheld blender or place ingredients into blender and puree add cream, butter, parsley and whip them to a fluffy texture season with salt and pepper and serve. They taste very much like mashed potatoes.
