Preheat the oven to 400°F. Line a baking sheet with parchment paper.
In a saucepan, combine the milk, water, and oil together and bring the mixture to a boil over high heat.
In a large bowl, combine the tapioca flour, salt, egg and grated cheese.
Transfer the milk mixture from the saucepan to the bowl with the flour mixture and stir until the batter is smooth. Using your hands, form balls from the dough about 1" big. If needed, add additional flour, a small amount at a time, if the dough is too sticky.
Place the dough balls on the baking sheet and bake them for about 20 minutes or until they turn golden. Serve warm.
Notes
I like to use a sharp cheddar cheese blend, which gives the bread balls a nice color, but you can also switch out the cheddar for parmesan or gruyere.
