Beans (canned or boiled in a glass), tomatoes in their own juice, fish, seafood and olives are added to the pan, let it boil. Add about a tablespoon of salt (olives are salty!), half a teaspoon of sugar and a couple of tablespoons of olive pickle. Let the soup boil for 3 minutes and remove from the heat. I also usually put a couple of basil sprigs for flavor.
