I know this says Omlette but that is what they are called in Swiss! (pronounced om-le-tteh). They would be thin pancakes or crepes in Oz. We usually fill with sliced fried mushrooms and cheese. I had a really nice one last night with Nutella and crushed nuts! Yield will depend on the size of your pan and how thin you can make them (and how many you want to eat! We usually have 2-3 each)
