In a bowl, combine the milk and breadcrumbs. Set aside for 5 minutes.
In a large bowl, combine the chicken, crumbled feta, grated zucchini, lemon zest, egg, minced garlic, breadcrumb mixture, salt, chopped herbs and a pinch of black pepper.
Mix and use a cookie scoop to scoop into balls. Pour olive oil in a shallow dish and rub your hands in it. Roll the balls in your hands to coat in oil.
Preheat the air fryer or oven to 400℉. Place the meatballs on a baking tray in the top third of the oven and bake for 11 minutes in the airfryer or 12-15 minutes in the oven until golden brown and cooked through.
