Bring the milk, olive oil, and salt to a boil in a pot.

Pour the hot liquid mixture over the tapioca flour and stir until you get a sticky, smooth dough; let the dough cool down.

Once the dough has cooled, add the eggs one by one, then the grated cheese last, kneading until you get a uniform mixture.

Shape the dough into small balls and arrange with space between them on a parchment-lined tray, then bake in a preheated oven until lightly browned on the outside.
