In a bowl of a stand mixer, mix together the flour, salt, and baking powder using the paddle attachment.
Once this is mixed, add in the milk and slowly pour in the water until it reaches a good consistency (start with 1/2 a cup). Using the gluten free flour, I had to use a full cup.
Cover and let it rest for about an hour.
Once you are ready to make the bread, using a cast iron skillet, heat up the oil on medium-high heat. I typically will add about 1-2 inches of oil enough to cover half the bread.
Grab a handful of the dough, then spread it to the size you prefer. These were about 5 inches across for me when I was making them.
Place the dough in the oil and let it fry on one side about a minute then turn and fry on the other side.
Place on a paper towel lined plate until ready to serve.
This should make about 6 fry bread; however, it will vary depending on the size.
Once they are done, top with your taco toppings and serve with dressing.
