Cut up your lovely cauliflower into pieces, about two to three inches in size. Fill a large pot with about an inch of water, and then put a colander in the pot. Add your cauliflower pieces to the colander, cover the pot and turn it on high and let the cauliflower steam until it is tender, about 10 minutes or so. You can check it by piercing one of the pieces with a paring knife...it should go in easily.
