Heat 1 tbsp oil in a large pan, then fry the onion and garlic over a low heat for 5 mins until softened. Tip into a large mixing bowl with the chickpeas and spices, then mash together with a fork or potato masher until the chickpeas are totally broken down. Stir in the parsley or dried herbs, with seasoning to taste. Add the egg, then squish the mixture together with your hands.
