This is an awesome and filling dip to have in your fridge for when the urge to munch arises.
Drain most of the cooking water and place the cooked chickpeas in a food processor or blender. (Keep the drained water aside for liquefying if required).
Add the lemon juice and garlic. Pulse briefly, until the chickpeas are slightly chopped.
Add the onion and pulse again until the mixture is chunky.
Place the mixture in a bowl and add the remaining ingredients. Mix well. Cover and chill before serving.
