Preheat oven to 400°F (200°C).
In a large bowl, combine ground chicken, breadcrumbs, parmesan cheese, garlic, egg, olive oil, salt, and pepper.
Mix until well combined.
Form the mixture into small meatballs, about 1 inch in diameter.
Place meatballs on a baking sheet lined with parchment paper.
Bake in the preheated oven for 20-25 minutes, or until fully cooked and golden brown.
Serve hot as an appetizer or with your favorite sauce and pasta.
