I'm also interested in a recipe for simple flatbread.
In my case, I use a bread machine to knead dough because my hands don't work well enough. I have conferred with a consultant on King Arthur Flour's Bakers Hotline who searched through their published recipes to identify which recipes can be done with the bread machine.
They are:
Quick and Easy Flatbreads
Naan
Soft Wrap Bread
Sourdough Naan
Can't say much about these recipes as I haven't actually made any of them yet. 🙄
Edited to add that I don't know how the KAF consultant chose bread-machine or no-bread-machine for the flatbread recipe, i.e. what the selection criteria was.
