Mix the semolina and curd in a bowl. Keep it aside for half an hour minimum. The consistency shouldn't be too liquid.

Chop all the vegetables into small cubes. Add green chillies and coriander leaves to this.

Now in a dosa pan, add 1/4th teaspoon oil, add mustard seeds to it. Let them pop.

As soon as the seeds pop up, add the batter and spread it evenly. Cover it with the pan.

Serve hot along with green chutney or ketchup.
