Heat the coconut oil in a large pan, then add the onion and cook for a few minutes until softened. Add the garlic, chilli, ginger and spices, along with a good dose of salt and pepper, then stir well and fry gently for a further couple of minutes.
Add in the tomatoes, chickpeas, coconut milk and sweet potato, stir and turn the curry down to a simmer. In the meantime, finely chop a small handful of the coriander stems, then stir those in too, before adding the juice of half a lime. Cover the curry with a lid for around an hour, stirring often and adding more seasoning and spices to taste (I usually add a touch more cinnamon and chilli flakes).
Just before you’re ready to serve, stir through the Co-Yo, along with more lime and spices if desired. Serve scattered with coriander leaves and with boiled rice or Quinoa and enjoy!
