Cauliflower Alfredo substitute

K frankly there are a lot of recipes out there for this.  I used a really basic recipe which was basically a bunch of cauliflower boiled for a while and then blended with some of the water and add garlic.  I was supposed to add milk but forgot and I still thought it turned out pretty good although my family were not fans.  I want to experiment a little bit.  I just saw a recipe that added nutritional yeast to it.  So, if I find another recipe that everyone loves or at least tolerates a lot better I will definitely post it.
