Put the pumpkin seeds in a sieve and rinse to remove any pulp. Spread out on a plate and pat dry. Toast 50g of the seeds in a pan over a medium heat along with the oats and 1 tsp each of the coriander seeds and chilli flakes for a few minutes until fragrant. Stir in the tamari and maple syrup. Simmer for 30 seconds until reduced and sticky. Transfer to a plate.

Heat the oil in the pan over a medium heat and cook the onion, celery, carrots, garlic and pumpkin, along with the remaining spices and some seasoning for 10 mins. Pour in the stock. Bring to a simmer and cook with the lid on for 20-25 mins.

Blitz until smooth using a hand blender. Serve with the savoury granola sprinkled on top.
