The courgette adds softness and moisture to the recipe, without changing the taste. In short, I find that this vegetable adds a little extra to the dough. Moreover, it is a clever way of getting young and old to consume a vegetable without really noticing it.
This dish can be eaten as an appetizer or as a main course with a nice seasonal salad. It will surprise you with its mixture of flavours and you will see that the apple mixes well with salty flavours (and just as well in a salad of seasonal raw vegetables).
