Hot dog

A hot dog is a kind of food made with a cooked sausage (made from meat) and a bun (a kind of bread). It's usually served with ketchup, mustard, onions and relish (kind of like pickles). The sausage is usually cooked by boiling or grilling it. You put the sausage inside the bun, then put the toppings on top. Then you eat it and it's really delicious!
