Firstly take a wok and dry roast the oats for 5 to 7 minutes.
Take a mixer jar add oats,buttermilk,salt and black pepper powder and go for a smooth blend.
Take a non stick pan add 1/2 tsp oil and spread the batter ,cover the pan with a lid for 5 minutes.
Now sprinkle rest of the 1/2 tsp oil on the chila and flip it to cook it from the other side.
when you will find the chila have turned crispy and changed the color,it means its done.
