Continuing adventures in low-carb vegetarian cooking

So today I was very excited to try vegangela's Mashed cauliflower with roasted garlic, mainly due to volume. (Dude, you can eat a whole cauliflower and it barely counts on the glycemic index!) Now, my sister, who has done South Beach before, warned me that eating mashed cauliflower with mashed potato expectations was setting myself up for disappointment, so I was prepared, but I like cauliflower ok and love roasted garlic, so I had high hopes.

Unfortunately, the vegan version of this did not live up to expectations--I even bought nutritional yeast for the first time, and it did add an interesting flavor, but overall I rated it kind of bland until I added half a cup of low-fat yogurt. Then it was fairly yummy (plus I had the sensation of being transgressive even though dairy is perfectly ok on my diet). I can see, though, if I were craving mashed potatoes, I could make this with milk and a little cheese and it would definitely hit the spot.
