"Minestra Maritata" translates to married soup. The ingredients blend or "marry" well together, hence the name Minestra Maritata. I'm sure that someone not knowledgeable with the Italian language translated it to "Italian Wedding Soup." It is not a soup Italians serve at weddings. In this recipe, the escarole is cooked separately to remove some of the bitterness and to keep the soup from turning green.
