In a bowl, combine chickpea flour, sliced green onions, chopped red onion, chopped green chili, chopped cilantro, red chili flakes, and salt.
Gradually add water to the mixture, stirring until a thin, crepe-like batter consistency is achieved.
Heat a non-stick pan over medium heat and add a tablespoon of oil. Let the pan get really hot.
Pour two ladlefuls of the batter onto the pan and quickly move the pan around to spread the batter to cover the surface. The batter should sizzle when it hits the pan.
Let the pancake cook on one side for 2-3 minutes until golden brown and crispy on the underside. Run a spatula along the edges of the pancake to release it before flipping. Let the other side cook for another 2 mins. Then flip twice more cook for a minute each.
Serve as is with mint chutney or add cheese to the chila and fold it in half.
