My daughter Jamie loves this mac n cheese! She is a vegetarian so I often make more of this so she will have plenty for leftovers. It is super simple and tastes amazing! You can use any cheese you like, different combinations work very well. Do not use the pre-bagged kind. It contains cornstarch and won't work in this recipe. It might seem like too much cheese, but trust me, it works! I hope you love it as much as our family does!
