Saj is like a big flat pan that you cook bread on. It's usually made of metal or cast iron and has no sides, like a plate. You put the saj on a gas stove or over hot coals and then you slap some dough onto it. The dough flattens out and cooks quickly, turning into flatbread. Then you can put all sorts of delicious things on the bread, like cheese or meat or veggies, and roll it up to eat it like a sandwich. Saj is a fun and easy way to make yummy bread at home!
