Okay kiddo, kabab barg is a yummy Iranian dish made from small pieces of beef or lamb that are marinated in spices, like saffron, and grilled on a skewer over an open flame.
The meat is cut into thin strips and then threaded onto the skewer with onions and tomatoes. The skewer is then placed on a grill and cooked until the meat is charred on the outside, but juicy and tender on the inside.
Once the meat is cooked, it is served with rice or bread and some fresh herbs and vegetables. It's a really popular dish in Iran and many people love it because it's simple, but really tasty!
