My college from work Branka mentioned this to me, since I have a surplus of zucchinis.
3 larger zucchinis
3 whole eggs
1 piece of young slty cheese (about 300gr)
Peel zucchinis, and cut the to 3mm thickness.
Mix eggs with grinded cheese, add salt and dill (per taste).
In the oiled casserole, layered with backing paper, add a layer of zucchinis and layer of this mix until you have used it all up.
Bake in a preheated oven at 180C.
