In a large bowl, mix the breadcrumbs and milk. Let it sit for 1–2 minutes until soft.
Add grated onion, garlic, egg, parsley, dill, lemon zest, oregano, salt, pepper, and olive oil. Stir gently.
Add the ground turkey. Mix just until combined. Don’t overmix.
Roll the mixture into golf-ball-size meatballs.
Heat a pan with olive oil over medium heat or preheat the oven to 400°F (205°C).
Cook meatballs in the pan for 10–12 minutes, turning often, or bake for 18–22 minutes, flipping once.
Remove when fully cooked and lightly golden.
