Drain the chickpeas, peel the garlic and squeeze out the lemon juice. In other words have everything ready to hand!
Put all the ingredients in a blender and blend until smooth. Alternatively you can leave it a bit chunky. You might need to scrape down the side of the blender and blend again to make sure everything is mixed well.
Refrigerate for 30 minutes. Not essential, but blending can slightly warm foods through friction so I think it's nicer once cooled again and tasting fresh.
Serve with crudite - serves 2 for lunch or 4-6 alongside other foods other than vegetables
