Combine yeast, sugar and warm water in a large mixing bowl. Let it sit for 5 minutes to active the yeast.
Add flour, olive oil, and salt to the mixing bowl. Mix with a fork or wooden spoon until it has started to come together. Turn onto a floured flat surface and knead the dough for a couple of minutes until it becomes smooth and elastic.
Place the dough back into the mixing bowl and cover with a clean kitchen towel. Let the dough rise for 45 min - 1 hour.
Cut the dough in half and roll out the dough. You should have 2 flatbreads to work with. The dough should be rolled quite thin for flatbread.
At this point you can add any toppings to the flatbread. It is recommended that you brush the flatbread with a bit of olive oil before adding your pizza sauce.
Bake the flatbread at 450 degrees F for 7-12 minutes. The flatbread edges will be light-golden brown, and the cheese will start browning when it's ready to come out of the oven.
