In a bowl, combine all the flours together. Mix well.
Add the finely chopped vegetables, onions, flax seeds, sesame seeds, turmeric powder and red chilli powder.
Now add asafoetida, salt to taste and mix everything together.
Add finely chopped coriander leaves to this mixture and pour some water.
The batter consistency should be thick enough for pancakes.
Heat a non-stick pan, add few drops of oil and grease it with a kitchen paper or slice of potato / onion.
Now carefully place a spoonful of the thick pancake batter on the hot griddle, spread it evenly and pour oil on the sides to enable cooking.
Ensure the gas flame is low to medium as Sattu takes some time to cook.
Once the pancakes have cooked, flip and add some oil, allow it cook on the other side for sometime.
Serve hot with coriander chutney and/or tomato ketchup.
