You can also get a ricer (may have to go to a "fancy" cooking shop to find one, or order from Amazon) and rice cooked cauliflower yourself. It's much better fresh. You can also rice potatoes, turnips, rutibagas, carrots, all sorts of "solid" veggies.
I have one, but its about 30 years old and has seen much better days. If your diet allows, riced potatoes are very good, even better if mixed with riced turnip. They are fluffier than mashed, and don't' require all the cream and butter and stuff to be tasty.
RIced turnip or cauliflower makes a tasty, and healthier substitute for polenta/grits in a lot of dishes that call for them as a "base" for the main course.
Parsnips are also very good, but they are sort of an acquired taste and even more expensive than turnips.
