I always came after my "Great Granny" (she was like 98 years old) and this is one of the things i love. She made them everytime i visited her.
Its called "Schnibbelzkuchen". Like a big fat pancake with some potato stripes in and salt on top of it. i can eat like 2-3 of them.
In the picture is a smaller one my mother made... normally they are the size of the pan.
You fry the potato stripes a few minutes before you put the pancake stuff over them. You fill it up until the pancake is as fat as the potato stripes
