1. In a large bowl combine the flour and mashed potatoes until a nice dough forms that is easy to handle. Depending on how wet your mashed potatoes were you might need to sprinkle a little extra flour in there.
2. Sprinkle a little flour on your kitchen counter and place the dough on top. Use the palm of your hands to roll it out into a long log. Use a serrated knife to cut the log into 14-16 pieces depending on how small you like to make your flatbreads.
3. Sprinkle some more flour on each individual piece of dough and use the palm of you hand to flatten it. At this point use a rolling pin to roll them out as thin as you like without tearing them.
4. Meanwhile preheat a seasoned cast iron skillet or griddle on medium-low heat and cook the flatbread for a couple of minutes or so on each side until done to your liking. We prefer little charred spots on ours for crunch and a little smokiness.
5. Transfer the cooked flatbreads to a tea towel lined plate and wrap them nicely to keep warm and soft. Serve with your favorite soups as stews, make tacos, wraps, burritos etc...
