1. Mix all the above ingredients except oil in a mixing bowl.
2. Add enough water and make a batter out of it.
3. The batter should be a little more thicker than the dosa/idli batter.
4. Grease the tawa completely with a few drops of oil.
5. Take a handful of the above batter and spread it on the tawa with your hands.
6. Place the tawa on stove; cook covered on medium heat.
7. After about 1/2 - 1 min, pour some oil/ghee and cook covered for another 2-3 mins.
8. Remove from heat and serve hot with butter and green chutney or with any other sabzi of your choice.

Tip:

1. To make the next roti, hold the back side of the tawa under cold running water until it cools down; continue making the next one, as explained above.
2. You could even have two tawas and use them alternately for making rotis.
