In a small bowl, combine yeast, 1 cup of warm water, and sugar. Allow yeast to bloom for 10 minutes.
Meanwhile, in a separate medium mixing bowl, combine the flour and salt.
Once the yeast has bloomed, add it to the mixing bowl with the flour. The dough will be shaggy at this point.
Add the olive oil to the dough and use your hand to knead the dough in the bowl for 10 minutes or in a stand mixer with the hook attachment until the dough starts forming. See troubleshooting tips.
Add a drizzle of olive oil around your mixing bowl to coat the sides. Cover the bowl with a damp kitchen towel or plastic wrap.
Place the bowl in a warm place and allow to rise for 1 hour. Tip: Place the bowl in a cold oven with the oven light on - this will create a warm environment for your dough to rise.
Turn the dough over on a lightly floured surface, and divide into 8 equal parts. Fold in the sides of each piece and roll into a ball. Place onto a floured baking sheet and cover. Let the dough rest for 20-25 minutes.
Heat a Cast Iron on medium heat. I like to use avocado oil to grease the pan.
Take one ball of dough out onto the lightly floured surface and shape it into a round flat disk. Using your hands or a rolling pin, flatten the dough keeping it in a round shape - about 8 inches in diameter. Remember, once the dough hits the hot pan it will instantly shrink.
Place rolled-out dough onto the hot pan and allow the underside to cook for 2 minutes or until golden brown. Flip to cook the other side.
Remove the flatbread and set it aside on a cooling rack. Repeat steps 9 & 10 for the rest of the dough.
Optional: Before serving the warm bread, drizzle on some olive oil and sprinkle on some flakey sea salt.
