Place the bread in a bowl of water and allow it to soak for a few seconds. Using your hands, squeeze the excess water out of the bread. Place in the food processor.
Along with the soaked bread, add the onion, parsley and mint and mix until a soft paste forms.
In a separate bowl combine the ground meat, the bread paste, egg, garlic, olive oil and ouzo (if using). Using your hands, mix all the ingredients together until well combined.
Take one tablespoon of the mix, roll into a ball and place on the floured plate. Continue with the remainder of the Greek meatballs.
Heat the olive oil in a fry pan on a medium heat and shallow fry the keftedes until browned all over (this should take approx. 5-10 minutes).
Serve with Greek fries and a Greek salad to make it a complete Greek feast!
