saw these in the market. the sign says greenhouse water [generic word for melon], or water courgettes. They look more like cucumbers, although the flower at the top suggests strongly they are in the courgette family. Never seen them this long though.

I never peel courgettes but the skin on these were tough, so i did peel them. Sautéed them in olive oil with some leftover vegetables — pumpkin, carrots, chestnuts. Added half a spoon of red pesto for flavour. Very easy dish to make, very healthy, very tasty. And the water courgettes taste just like regular courgettes, only a little more watery.
