This is very similar to the Smashed Cauliflower sticky. I may merge the two threads.
I estimate this as four servings. I just ran the main ingredients through fitday. Made with a medium head of cauliflower, 1½ cups reduced fat shredded cheese and a cup of light sour cream, the whole recipe is 841 calories or 210 per serving - maybe a bit high for a veggie serving but OK for a main dish. (I did not add in the margarine which would make it higher.)
Change isnít easy. But if you donít change, you stay the same, and whereís the fun in that?
