Preheat a grill (broiler) to high. Cut off and discard the edge of the pitta bread, split the bread into 2 thin halves, and lightly brush all over with some of the oil. Place under the grill and toast until crisp and lightly browned.
Toss the sweet potato in the remaining oil and grill for 8–10 minutes, until soft and golden on both sides. Tran
