Cut your zolle in half and finely chop (avoid the woody bottoms!) put in a mixing bowl. If you are looking for an extra sweet flavour blanch them quickly first for 3 minutes before drying thoroughly.
Grate your 2 cheeses and mix in with your zolle.
Add salt, pepper, milk and a dribble of olive oil into to beaten eggs.
Mix well into your zolle and cheese mixture
Place 1 sheet of pastry in a round or rectangular pie tin and add your mixture on top. Add your pastry lid on top and crimp the edges in. Make 2 holes in the centre and brush with beaten egg.
Bake in a pre-heated oven for 35 minutes until golden brown.
