For the pumpkin salad, wash the pumpkin hot, cut away any ugly spots and remove the seeds.
Cut into bite-sized cubes and place on a baking sheet lined with parchment paper. Rub with a little olive oil.
Crush coriander seeds, chili pepper, salt and pepper in a mortar and sprinkle over the squash.
Bake at 190 degrees for about 30 minutes until soft and golden brown. Cover four plates with arugula, arrange the squash cubes and ham on top.
Drizzle with olive oil, balsamic and sprinkle with salt and pepper. Arrange the pumpkin salad with Parma ham and garnish with Parmesan shavings.
