Start by boiling the soaked chickpeas in a pressure cooker or a large pot until they're soft and easily mashable.
Heat oil in a pan and add the finely chopped onions. Sauté them until they turn a golden brown.
Add the ginger-garlic paste and green chilies to the pan and stir until the raw smell disappears.
Now it's time to add the tomatoes, turmeric, chili powder, and the star of the show, the Chana Masala powder. Cook this mixture until the oil starts separating from the masala.
Add the boiled chickpeas to the pan and mix well so that they are coated with the masala. Add some water and salt, then let it simmer for about 15 minutes until the flavors meld together.
Garnish your dish with fresh coriander leaves.
