Cut each string cheese stick into four equal pieces, yielding a total of 24 cheese bites.

Arrange three bowls: one with flour, one with whisked eggs and a splash of water, and one with breadcrumbs mixed with herbs and salt.

Dip each cheese piece into the flour, then into the egg mixture, ensuring to coat well.

Roll each cheese piece in the breadcrumb mixture until fully coated.

Place the coated cheese balls in a single layer in the air fryer basket and lightly spray them with cooking spray.

Cook in the air fryer at 375°F for 8-10 minutes, until golden brown.

Let the cheese balls cool for 1-2 minutes before serving.
