Preheat your oven to 375°F (190°C).

In a large mixing bowl, combine the tapioca flour and salt.

In a saucepan over medium heat, combine the milk and vegetable oil. Bring to a gentle simmer.

Pour the heated milk mixture over the tapioca flour and salt. Stir until combined into a dough-like consistency.

Let the mixture cool slightly, then add the eggs one at a time, mixing well. Fold in grated parmesan cheese.

Shape the dough into small balls, about the size of a golf ball.

Place the balls on a greased baking sheet, leaving space in between. Bake for 20 to 25 minutes, or until golden brown.

Let them cool for a few minutes before serving.
