In a mixing bowl, combine the oat flour, besan, chopped onion, turmeric, ajwain, and salt.

Gradually add water until the dry ingredients are combined and you get a slightly thick batter.

Heat a non-stick pan after spreading some oil on it.

Spread a ladle of batter on the pan in a round shape.

Cook both sides for 2-3 minutes on medium flame until they are light brown.

Serve hot with yoghurt or green chutney.
