For the turmeric paste, combine all the ingredients into the Vitamix 600ml blending cup, screw on the base and blend on speed 2 then increase to speed 7-8 to form a smooth puree (about 30 seconds).
Pour this into a small pot and cook over a medium heat for 5-7 minutes, whisking, to reduce and thicken then pour that into a jar or container, allow to cool and store in the fridge up to 1 month.
For the curry, place a medium saucepan over a medium/high heat and add the onion, veggies and good pinch of salt. Cook this for 3-4 minutes, stirring often, then add the turmeric paste, stirring and cooking for 2 more minutes. Add the vegetable stock, coconut milk and simmer, covered for 7-8 minutes, until the veggies are cooked.
Add the chickpeas and simmer uncovered for 2-3 minutes.
Finish with the coriander, lime and serve with steamed rice, yoghurt and papadums if using.
