So I have to admit this is not my recipe it's my husbands!  He thought of this recipe all by himself.  The idea came to him the day I made the macaroni and cheese for Anthony.  We love Italian food and macaroni and cheese so this is a marriage of our two favorite things. He used quattro formaggi cheese which just means in Italian four cheeses.  You can use whichever four cheeses you like, he choose a shredded package of cheese which included mozzarella, provolone, asiago and parmesan.  I loved all the ingredients separately so I had high expectations for this dish.  This meal surpassed all my expectations it was absolutely the best macaroni and cheese I have ever had!  It was the right amount of gooeyness from the cheese and the fresh tomatoes hidden in the little pockets of the shells was a nice surprise.  This was a nice treat from the hubby that only make two meals once a year now we are up to three.  I will definitely request this again!
