  • Add to the seeds mixture the hazelnut flour, the buckwheat flakes, chopped sage leaves, and salt. Mix with a spoon and add a tablespoon of oil or two if it doesn’t hold together. It has to stay together in chunks, that will become our granola chunks.
  • Place the pumpkin slices on a tray with parchment paper and drizzle them with some oil, then add some sage leaves and salt. Place the tray on the bottom of the oven.
  • Place on a second tray the granola mixture well layered and spaced here and there. Place the tray on the higher level of the oven.
  • Bake everything at 180°C/350°F for 30 minutes.
  • Remove the sage leaves from the pumpkin and blend it with a mixer until smooth. Add some hot water if needed to adjust the texture. Add salt to taste.
  • Serve in bowls with a drizzle of extra virgin olive oil, crushed pepper and the granola chunks.Zero waste pumpkin soup
