Preheat your oven to 200°C (400°F) and line a baking sheet with parchment paper or lightly grease it with olive oil.

In a small bowl, combine breadcrumbs and milk, then let sit for 2 minutes to soften.

In a large mixing bowl, add ground chicken, soaked breadcrumbs, Parmesan, egg, minced garlic, chopped onion, parsley, oregano, salt, and black pepper. Mix until just combined, avoiding overmixing.

With wet hands or a cookie scoop, form the mixture into small balls, placing them on the prepared baking sheet.

Brush or drizzle the meatballs with olive oil.

Bake in the preheated oven for 18-20 minutes, or until golden brown and cooked through, checking that the internal temperature reaches 74°C (165°F).

Alternatively, heat olive oil in a skillet over medium heat and cook meatballs in batches for 10-12 minutes, turning to brown all sides until cooked through.

Serve hot with your favorite sauce or over pasta, rice, or in a sub roll.
