Mix all ingredients for the pesto except parmesan cheese to a somewhat grainy pesto (save some of the nuts for decoration). Add the finely grated parmesan cheese and stir to combine. Season to taste with salt & pepper.
Slice the figs, cucumber and mozzarella. Layer on a large serving plate. Drizzle with pesto and decorate with chopped nuts, flakey sea salt & pepper. Enjoy!
