Add the yeast mixture to the spiced flour mixture and enough additional water to form a slightly firm dough.
Warm a large frying pan or skillet, add oil, and warm until shimmery.
Add the drained chickpeas and cut potato, and stir to coat with the spice mixture and cook for another five minutes.
Finally, assemble your doubles by placing one bara on a plate, spooning
the chickpea filling on it and then place another bara on top.
