I got this recipe from the "Shut up and Mangia" website. ZAAR is my favorite website to save all my recipes to. The author writes: "One of my old family recipes is this mostaccioli and cauliflower dish. My Grandmother made this dish for almost every occasion. It's different and delicious. I never ate ham when I was younger, so when I went to my grams house she alway made sure that I something other than the ham to eat. I'm the only one who still makes it. But, as soon as my cousins in California and New Mexico find out I have the recipe I'm sure they'll try to make it themselves. This combination can be made two ways. You could mix the ingredients to be very thick and creamy with no trace of cauliflower or you can mix it and leave larger pieces of cauliflower. Which ever way you decide to make it I can assure you it's a very filling dish. I make this recipe at least once every two weeks. The kids are just starting to enjoy it but I'm sure they will be making it for their children in the future."
