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.

Frittata is an egg-based Italian dish similar to an omelette or crustless quiche or scrambled eggs, enriched with additional ingredients such as meats, cheeses, or vegetables. The word frittata is Italian and roughly translates to 'fried'.
