When my daughter was little, she used to call this "macaroni and home-made cheese" much to the delight of her grandmother with whom the recipe originated. Grandma always used Velveeta, but we usually use cheddar. I have used whatever I have on hand. Monterey Jack is especially good. Use your favorite cheese. This recipe takes little more effort than a box, is faster than frozen, and is oh so much better than both. Everyone will think you cooked all day.
