For the flatbread: In a small mixing bowl, add the self-rising flour, yogurt, olive oil, rosemary and salt and mix. It might seem like the consistency is sticky, but this is okay!
Dust a bench top with more of the flour and knead the dough until it forms a ball. If it's still sticky, add more flour to the bench. Roll out the dough with a rolling pin until 1/2 centimeter (1/4 inch) in thickness.
Heat a small splash of olive oil in a small pan over medium heat. Once hot, transfer the flatbread over and cook until light brown, about 2 minutes. Then flip and cook on the other side for another minute. Serve topped with one of the pizza topping combinations.
