Method
Prep:15min  ›  Cook:20min  ›  Ready in:35min 

1. Preheat oven to 200 C / Gas 6. Grease a 23cm square baking dish with 1 tablespoon of extra virgin olive oil. Set aside.
2. Slice the courgettes very thinly lengthways, using a knife or mandoline. Divide in 3 equal bunches.
3. Lay the bottom of the dish with the first bunch of courgette slices, side by side. Season with salt. Cover with 1/3 of the mozzarella, 2 slices of ham and 1/2 of the feta. Sprinkle with 1/3 of the Parmesan cheese.
4. Cover with a second layer of courgette slices and proceed as for the first layer. Finish with a third layer of courgettes, season with salt, add the remaining 1/3 of mozzarella and sprinkle with remaining 1/3 of grated Parmesan cheese.
5. In a bowl whisk together the egg, milk, salt, pepper and nutmeg. Pour over the lasagne, covering top and sides.
6. Bake for 20 to 25 minutes or until the top is golden brown. During baking, the courgette will release water; if you notice this, remove from oven and carefully drain, then return to oven to continue baking.
7. Remove lasagne from the oven, let stand for a few minutes before slicing, then serve.
