Haha it's such a versatile dish it's hard to give you an exact list of ingredients! The most common way to make it is with bread(?) flour, but at home we also make it with corn flour sometimes. You add eggs, and then you can choose, for example, between thinly cut leafy vegetables like kale (very common here) or sliced carrots. Add yummy oregano and salt. I personally don't, but some people add meat like slices of sausage to increment it.

It's hard to describe, I'll have to post a recipe for it later :P My dad makes an extra good one, I'll ask him about it :)
