Sangak (or nan-e sangak) is a plain, rectangular, or triangular, blanket-like Persian flatbread. 'Sang' in Persian means stone or pebble and 'sangak' means related to sang. This bread is traditionally baked on river stones (hence the name), and is occasionally topped with sesame seeds.
Sangak bread was traditionally the bread of the Persian Army. Each soldier carried a small bag of pebbles which at camp was brought together with the "sangak oven" and formed to cook the bread for the entire army. Sangak Bread and Kabab (meat BBQ on coal skewered with a "sword") is still a staple food of the Iranian Army today.
