My mother used to make mac n' cheese with mozzarella, ricotta cheese and tomatoes -- although her's was a lot higher in the calorie/fat count than this delicious version, everyone gobbled this one up! At first the green spinach seemed a bit strange and unfamiliar in mac n' cheese, but my family got past that in a hurry as they filled their plates up with more of this mac n' cheese. Although the original recipe called for capellini, but I used rotini, which looks more like the traditional mac n' cheese that we know and love. Recipe source: WW Magazine (March 2008) If you are following the WW flex plan this is 6 points/serving. Sometimes it's hard to find fat-free cheese, you can also use part-skim or skim cheese and add a point or so if following the WW flex plan. I used part skim mozzarella and part skim ricotta and I counted it as 8 points.
