Eggahs-Arab omelettes- are rather similar to the Spanish tortilla. Whether the Moors took them to Spain, or brought them home again, nobody quite knows but almost every country has their own variation. In Tunisia they add a highly spiced sausage and dried chillies and stir the eggs until it is rather like firm scrambled eggs. You can use a spicy chorizo in this very successfully. This originated from The Complete Meze Table.
