Delicious, carroty mac and cheese. It makes maybe 5 portions, so it is a much more reasonable size than M's family recipe, which calls for 1 lb of mac and 2 of cheese. I usually make it with skim greek yogurt rather than sour cream, which works fine. One child doesn't seem to notice the carrots, the other does and screams and cries for boxed shells with cheese, so... some success?
