This is simple and delicious. I'm not a spicy food fan, so just used a pinch of cayenne. I diced the sweet potatoes to approximately the same size as the chickpeas and they were perfectly cooked by the time the chicken was done. Next time I will cut the prunes in half or quarters so they look better with the other ingredients, and are easier to eat. Served over couscous, it needs a few sprigs of cilantro on top to add vivid color.
