Rach adds cauliflower (two heads!) to her super-creamy macaroni and cheese, and the result will have kids and adults alike asking for more, please! It's also quick and easy to make and VERY cheesy. Mac and cheese is traditionally thickened with flour. Her version skips that ingredient (and all the stirring!) by subbing in Neufchatel cheese. If you can't find it, you can use reduced-fat cream cheese.
