TweetActually, there are even better ways.
1. Prepare Cauliflower about the same way you would potatoes for mashing. Cook it until it is mushy, add some heavy cream and butter and it makes a great substitute for potatoes.
2. When I was in cali I could get Celery root. Steamed and mashed in almost the same way, but does have a slight celery taste to it... but not bad.
3. You can also use the Cauliflower as a rice substitute. Very lightly cook it and break it into very small pieces (like in a food processor). Cook it just enough to break it down so it's not hard, but not so much that it is mushy.
4. As far as pasta is concerned... Spaghetti Squash... umm better than real pasta anyway.
