I shop from a Pakistani grocery sometimes and they sell Afghan bread there. It's a very long, soft flatbread. It's not thin like pita bread and it's not very thick like leavened bread.
The bread goes really well with curries, kormas and meat dishes. I think the bread is usually served with tandoori beef and chicken. The meat is cooking in the tandoor oven and so is the bread.
Although I enjoy this bread, I don't buy it every week because it's a little costly. We usually eat the bread very quickly so one rectangle doesn't last long. I do recommend it to those who have never tried it though. If you get it ready made, heat it up in the oven for a few minutes because it tastes even better when warm.
