In a small bowl, mix coconut oil, turmeric, black pepper, chilli and ginger.
Add pumpkin and some of the fibres (they will be tastier that way) to another bowl. Pour the mixture of oil and spices over them and mix well till well coated.
Transfer the mixture to the baking tray, distribute it evenly and pour over all the oil that remains in the bowl.
