Notes
Depending on your personal preference, you can use plain yogurt or Greek yogurt to make the yogurt sauce. Make sure you get the consistency of the yogurt sauce right. It shouldn’t be too thick or too thin. To loosen it up, you can add a dash of water. Soaking dry chickpeas overnight in some warm water can soften them up, and can quicken the cooking time. If you have any leftovers, you can store them for up to a day in the refrigerator. Since this chaat has yogurt, it can start to get sour with time, which is why I would recommend finishing it up quickly.
