Add the broth, salt and pepper and cook over low heat for 30-40 minutes. It can be served in 2 ways: 1. Without cheese: put the slices of bread in the tureen, pour the wine over the bread and then the onion soup (we can replace the wine with port). 2. In individual guest plates or tureens, pour the soup and wine. Add the toasted bread slices and cheese slices on top, trying to cover the soup with the bread and cheese.
