In a mixer jar, add ½ cup soaked kala chana, some coriander stems, some curry leaves, and 2 tbsp water. Grind it coarsely.
Transfer the mixture to a mixing bowl and add 1 tbsp green chilli–ginger–garlic paste, ¼ cup chopped onion, ¼ cup coriander leaves, ½ tsp cumin seeds, ½ tsp fennel seeds, 1 tsp sesame seeds, ½ tsp red chilli flakes, ½ tsp turmeric powder, 1 tsp coriander powder, ½ tsp chaat masala, 2 tbsp curd, and 1 tsp lemon juice. Mix well.
Add ¼ cup jowar flour and ¼ cup bajra flour. Mix well and knead a soft dough.
Take a small portion of the dough. Wet a nylon cloth, place the dough ball on it, and spread it with wet fingers to make the paratha.
Heat a tawa and spread a little ghee. Place the paratha on the tawa, remove the wet cloth, and roast it with ghee on medium-high flame until it turns slightly brown on both sides.
Kala chana paratha is ready. Serve with curd.
