Preheat your oven to 375°F (190°C).
In a large bowl, combine all of the ingredients: ground chicken, breadcrumbs, egg, lemon juice, garlic, onion, parsley, olive oil, salt, oregano, dill, and black pepper. Mix well until everything is evenly combined.
Form the mixture into 24 to 28 evenly-sized meatballs, about 1 to 1.5 inches in diameter.
Place the meatballs on a lined baking sheet, ensuring they are spaced out properly.
Bake the meatballs in the preheated oven for 22 to 25 minutes until lightly browned on the outside.
Once done, remove the meatballs from the oven and let them cool for a few minutes.
For a complete meal, serve your Greek Chicken Meatballs with fresh tomatoes, cucumber, tzatziki, and your favorite grain.
