Courgette is one of the lightest vegetables in the kitchen — a whole cup is about 21 calories — which is exactly why it works as a pasta substitute in ribbons. It is mostly water, so it releases liquid in the pan; salt it and pat it dry if you want it to brown rather than stew. It absorbs whatever it is cooked with, oil very much included.
