From www.TopSecretRecipes.com It's finally here! What everyone's been waiting for! Just in time for winter, this soup is sure to warm your soul with it's savory flavor and wonderful aroma. I've asked many an Olive Garden waiter for this recipe, but none gave it to me in detail. One waiter told me the secret ingredient was to add a little red wine to the stock, but I'll leave that up to you to try.
