Potato-Rosemary Skillet Flatbreads

This satisfying skillet flatbread recipe is wonderfully soft thanks to the inclusion of mashed potato. The addition of Manchego, a Spanish sheep’s-milk cheese, gives the flatbreads a subtle, salty tang, though you could substitute freshly grated Parmesan or another dry grated cheese. For gluten-free skillet breads, use a gluten-free flour blend in place of the all-purpose flour.
