An omelette is a dish made from beaten eggs fried and folded around fillings such as chives, vegetables, mushrooms, meat, cheese, or onions.

Kuku or kookoo is an egg-based and often vegetarian Iranian dish made of whipped eggs folded in various ingredients. It is similar to the Italian frittata, the French quiche, or an open-faced omelette, but it typically has less egg than a frittata, and it cooks for a shorter amount of time, over a low heat, before turned over or grilled briefly to set the top layer. It is served either hot or cold as a starter, side dish or a main course, and is accompanied with bread and either yogurt or salad.
