Cauliflower Pasta

I looked through my recipes for awhile, wanting to do something a little different with the cauliflower I had picked up on sale... I ended up with a take on Rachel Ray's Pasta w/Cauliflower Sauce. For two servings, I used 4oz penne (Barilla Plus), a little over half of a small head of cauliflower, water instead of stock, half of yellow onion instead of red, fresh thyme instead of rosemary, and goat cheese instead of romano. Apparently I didn't look too closely at the recipe when I decided to go for it! haha. Anyways, I was actually quite surprised at how tasty this turned out, despite the bland colors. Purple or orange cauliflower would be quite delightful in this!
