Then add the flour, the grated cheese and half a sachet of baking powder for savory pies.
Season with salt, pepper and nutmeg.
Preheat the oven to 180 ° C (356 ° F).
Then grate the courgettes in julienne form and add them to the mixture.
Cut the mozzarella into cubes, remove excess liquid and add half of it to the bowl.
Pour everything into a hinged pan, level and garnish the surface with the remaining mozzarella. Then add also some grated cheese.
