Prepare: Remove the ends from the courgette/zucchini and fennel and then peel the courgette. Chop the courgette, fennel and celery into small (ish) slices. Remove the leaves from the mint and discard the stalks.
Cook: Gently heat the coconut or olive oil in a pan over a medium heat and add the courgette, fennel and celery. Cook for 5 minutes, stirring occasionally until the vegetables start to soften, then add the salt, pepper and water, reduce the heat and continue to cook for a further 5 minutes.
Blend: Remove from the pan from the heat, add the fresh mint and blend for 1 – 2 minutes using either a stick blender or a regular blender. However be very careful if using a blender as the heat creates a build up of pressure that can blow the lid off! Ensure you cover the lid with a tea towel and hold down firmly whilst blending to avoid this.
Serve: Pour the soup into a bowl and enjoy!
