Add the meatball ingredients to a food processor and blitz until smooth.
Take walnut-sized amounts of the chicken mixture and roll in your hands to make smooth balls. The mix should make 20 meatballs.
Spray a frying pan with low-calorie cooking spray and set on a medium heat. Add the meatballs and cook for 10-12 minutes turning to brown on all sides. Check that the meatballs are cooked by cutting one in half to make sure the juices run clear.
While the meatballs are cooking, add the dressing ingredients to a small bowl and stir to combine.
Arrange the lettuce, cucumber and tomato on your serving plates top with the meatballs and drizzle with the dressing. Serve.
