Place all the ingredients in a food processor and blend for 5-10 seconds, until the mixture is fairly coarse. Push the mixture down with a spatula and blend for a further 10 seconds.
Wet your hands under the cold water tap and shape the mixture into 20 small balls.
Line a large baking tray with greaseproof paper. Place the balls on the tray and flatten slightly with the back of the spoon.
Bake for 15-18 minutes until lightly coloured. Remove from the oven and allow to rest.
