A classic "dutch oven" (cast iron, top and bottom) can and will make tasty bread, either in a standard oven or on a fire (tricky, but doable with practice). But don't limit yourself. Pita, and most, if not all, flatbread can be, and was for thousands of years, made on flat stones in a fire. Bannock, while now viewed as something special, has more relation to historical bread making than anything you can find in any store today.
