In the bowl of a blender, place all the stuffing ingredients, except the flour, parmesan and lemon juice.
Mix until everything is in small pieces (but not too much either).
Transfer to a salad bowl, add the lemon juice (the equivalent of a tablespoon), the flour and the grated parmesan. Mix with a fork until well combined.
Using your hands, form 16 chicken meatballs and place them in a dish.
