Add Oats in a blender and grind to a coarse powder
Mix all the ingredients and make a semi thick batter.
You should be able to spread it in the pan. It is a bit thick than dosa batter.
Let the batter rest for 10-15 minutes so that the flours hydrate.
Heat a pan and drizzle some oil on it.
Take 1 spoonful ladle and make a chila/pancake/dosa of around 5-6 inches or as preferred.
Cook it on slow gas for 5-7 minutes.
Flip when you see that the top is almost dry and it appears to cook. i.e. it starts leaving the edges of the pan.
Turn and again cook for 5-7 minutes.
Cook on both the sides until golden brown.
Serve it with Sauce or Chutney of your choice.
