I don't know why it is called "Chili" Soup but that is the name. I got this from my daughter and it is soooo easy and soooo delicious. Great for the long and cold winter evenings. Just have some crusty garlic bread or my Recipe #329435 to put it into. It calls for spaghetti sauce in a jar and I use Paul Newman's Sockaroonie. Yummmm!
