I'm not sure who I should attribute this recipe to. I believe I found it many years ago in Met Home Magazine. I love it... it makes a large meatloaf that will easily feed 8 people. And if you're fortunate enough to have left-overs the next day, it's really good cold. I have always made the meatloaf, layering prosciutto with the spinach but opted not to use prosciutto this time, and honestly, I didn't miss it.
