Add flour, salt, ajwain, and oil to a mixing bowl.
Mix them all well and start adding water little by little to knead a dough.
When the dough is kneaded into a smooth texture, leave it to rest for 30 minutes.
Now make stuffing: add sattu, onion, chilli, herbs, salt, coriander, and garam masala to a mixing bowl.
After adding lemon juice, sprinkle 1 tbsp of water to make a mixture.
Mix well: if the mixture has good moisture, then the filling is ready. If not, sprinkle more water.
Now make a dough ball from the kneaded dough.
Dust some flour on it and on the rolling board, and roll it into a small circle.
Apply some ghee and add a spoon of the mixture to the centre of a circle.
Now close the edges properly and roll it gently into a large roti.
Heat the tawa over high heat, and place the rolled roti over it.
After a few seconds, turn and apply some ghee on it.
Again, turn from the other and apply ghee this side too.
Cook from both sides until golden flakes appear.
When it starts appearing, remove the paratha immediately.
Serve it hot with curd or chutney.
