Preheat the oven to 400 degrees. Make the two ingredient dough: In a large mixing bowl, combine the flour and yogurt, stirring until they are well combined, using a fork, if necessary. If the mixture is too sticky, add a Tablespoon of additional flour and continue to mix. Repeat as necessary until the mixture becomes a workable ball of dough. Remove the dough from the bowl and knead on a lightly floured surface, until the dough is smooth.
