This is an old Campbell's Soup Recipe, but they quit making the Zesty Italian Tomato soup it called for. I found that jarred Spaghetti sauce was a good substitute. My entire family loves meatloaf, but thinks this is the tastiest, so far! I used to buy the Italian sausage in casings, remove the casings and crumble it up, but now you can buy it bulk. It calls for a sauce, but I have never made it - we didn't think it needed the addition.
