Saute the onions in a medium to large saucepan on oil until they become translucent.
Add the sweet potato and cook for a further 7-10 minutes until they are slightly soft.
In a blender add the spinach, tomatoes, garlic, ginger, garam masala, coconut milk, ¼ cup / 60ml of water, and chilli and blend until smooth.
Add to the saucepan and clean the rest of the sauce out of the blender with 1 cup /250ml of water and add to the saucepan. Cook for around 25-30 minutes, stirring occasionally until the sweet potato has cooked but isn’t falling apart.
Season to taste and serve with rice, naan, or quinoa.
