I just made this today after finding this recipe on Pinterest, and I loved it. I usually buy a big head of cauliflower every couple weeks, but most of the time it goes bad by the time I remember that it's in our fridge! With this recipe, I won't have a problem using a whole head of cauliflower every week!
Instead of putting parmesan on all of it, I did half with nutritional yeast seasoning because there are two vegans in my family, but I really think I liked it better with the nutritional yeast myself! Very cheesy flavored and delicious.
