Literally, SIX freakin' cans!! (It has been brought to my attention that there are only FIVE freakin' cans. Ooops, sorry. Usually I don't have a problem counting to five, but there you go. Enjoy the recipe anyway!)
Roasting the tomatoes, garlic and onions makes this soup especially flavorful. After the veggies are roasted, all you need is 40 minutes and you've got a robust, rustic-style soup.
