Rice and pasta made from veggies

Elissa was telling me that you can buy rice and pasta in the gluten free aisle of the supermarket that is made from veggies so it is virtually calorie free, but fills you up and is healthy. This made me think of a cauliflower rice that Pookey made for me a few months ago. It isn't great, but it gets you through the night, if you know what I mean.

Here is the cauliflower recipe - http://whatscookingamerica.net/Vegetables/CauliflowerRice.htm
