In a large mixing bowl, combine the flour, salt, and remaining tablespoon sugar. Add the yeast mixture, oil, and yogurt, and mix to combine. Knead the dough by hand on a clean work surface, adding more flour if needed, until it’s soft and slightly sticky, 7 to 10 minutes. Transfer the dough to an oiled bowl, cover with a plastic wrap, and let rise until it’s doubled in size.
