Place the chickpeas in a large bowl, cover with water. The chickpeas will swell by up to 3 times so ensure they are covered with ample water. Leave the chickpeas to soak over night.
Take the garlic cloves, place them on a chopping board and use the side of the knife blade to crush them, you don't need to cut them, just to break the clove up a bit, place the whole cloves, skin and all into the oil, and leave them to soak overnight

Rinse and drain chickpeas
Dry chickpeas with a tea towel, dry them very well and kind of rough them up a bit so that some of their papery skins come off.
Spread the dried chickpeas out onto a lined baking tray and toss them in the garlic-flavoured olive oil. Bake at 180 degrees Celsius for 35-40 minutes, or until crunchy
