Chop some beetroot into small pieces. Boil them until soft. Then blend them into a smooth puree.
In a bowl, mix besan, salt, chaat masala and beetroot puree.
Gradually add water to the mixture so that a thin, smooth batter starts to form.
For making the stuffing, mix paneer, chopped green chili, chopped onion, coriander, and chat masala in a bowl.
Heat a non-stick pan and grease it with oil.
Pour the batter onto the pan, making a thin layer and cook on medium heat.
Once the chilla turns crispy, sprinkle the stuffing on the top, then fold the chilla over the stuffing. Then serve it hot with chutney.
