Slice the courgettes as thinly as you can, a mandolin is great for this if you have one and feel confident to use without slicing your fingers!
Arrange the courgettes of a large flat platter.
Pile the rocket on top and scatter with pine nuts. Then drizzle over the olive oil and lemon juice, season to taste.
Add thin shavings of parmesan, omit if you want this to remain a vegan dish.
