In a bowl, whisk together the plant-based curd and besan until smooth.
In a pot, heat oil over medium heat. Add cumin seeds and dried red chillies, and sauté until fragrant.
Add the turmeric powder and green chillies, and sauté for a minute.
Pour in the water and bring to a boil.
Slowly add the curd-besan mixture, stirring continuously to avoid lumps.
Add salt to taste and simmer for about 20 minutes, stirring occasionally.
Once the kadhi thickens, remove from heat and garnish with fresh coriander leaves.
Serve hot with rice or roti.
