Broccoli, chicken or vegetable stock, a few slices of toasted bread, garlic, lemon, salt and pepper is all you need to make this tasty recipe from the "Soup Bible". (Broccoli grows abundantly around Rome and is served in this soup with garlic toasts.)
I made the soup with chicken stock (thanks, Lynn, for the chicken carcass!), added the optional parmesan and really enjoyed the soup. It had the right combination of spices.
