Mix chopped onions, minced green chillies, and cilantro in a small bowl.
Heat a pancake pan and pour a spoonful of batter over it. The pan should sizzle when you pour the batter. Spread the batter to cover the pan. Drizzle oil on all sides.
Generously sprinkle chopped onions, green chillies and cilantro mix on top. Press them lightly into the chilla. Do not flip to the other side in a rush. Keep the flame low to medium. Once the edges loosen up, flip and continue to cook. Cook each side evenly it for 2-3 minutes. Then take the pancake off the pan.
