Eggah is also similar to a frittata, Spanish omelette, Persian kuku or a French-style omelette. The frittata can be prepared with pasta leftovers, either with tomato sauce or white. Outside Italy, "frittata" was seen as equivalent to "omelette" until at least the mid-1950s. "Preboggion" is also sometimes added to minestrone soup and frittata. Tunisian tajine is more like an Italian frittata or an eggah. The Italian word "frittata" derives from "friggere" and roughly means "fried".
