Peel (if necessary) the vegetables and cut into small chuncks. Place them into a food processor and process into a large crumb.
Add the coconut oil to a pot and gently fry the coarsely chopped vegetables until soft.
Now add all the sauce ingredients and spices and gently boil for about 15 minutes until all the vegetables are soft.
In the meantime cut the chicken thighs into small chunks and fry in coconut oil until slightly browned and just cooked through. If serving with basmati or jasmin riuce, boil your rice now. Add the additional coconut oil (this is potional but will create that buttery mouthfeel of traditional butter chicken recipes) to the sauce. Puree the sauce super smooth or leave as it.
Add the sauce to the fried chicken or, if doing the vegan version, add the vegan chicken chunks to the sauce.NOTE: if adding the vegan chicken chunks to the sauce, you may want to add some chicken or vegetable broth as the chunks will thichen the sauce.
