Mix the yeast and water together in the bottom of a stand mixer.
Add the whole wheat flour and stir until fully combined.
Cover the bowl with plastic wrap and let sit for 30 minutes to 8 hours.
Sprinkle the salt over the top of the mixtures.
Add the oil.
Mix with a spoon or dough whisk.
Add the flour, one cup at a time, and stir. When you can no longer stir with a spoon, move the bowl to the stand mixer, and using the dough hook, knead for about 8 minutes. You can also knead by hand.
The final dough should be fairly firm and shiny.
Let the dough rise in an oiled bowl or bucket until doubled in size, about 2 hours.
Preheat the oven to 500 degrees F with a pizza stone on a rack placed on the lowest rung.
Once the dough has doubled, divide it into four pieces and cover each piece.
Working with one piece at a time, divide it into four pieces and form each piece into a ball. Press or roll each ball into a 6 to 8 inch disk.
Bake each disk for up to 7 minutes flipping half way through. Each piece should puff up as it is baking.
Cool each piece on a cooling rack, covered with a towel.
Enjoy!
