Roast duck

Roast Duck is a very common dish, eaten by Earth Kingdom and Fire Nation citizens. The Fire Nation eats after cutting it into bite-sized pieces, while the Earth Kingdom eats it whole with a special sauce. Roast Duck was first introduced in "The Boy in the Iceberg", when Iroh told Zuko that he will teach him advanced Firebending techniques after he finishes his bowl of Roast Duck. It was seen twice more in "The Cave of Two Lovers", when Song and her mother served it to Zuko and Iroh, after Iroh accidentally poisoned himself and in "The Serpent's Pass", when Zuko, Iroh and Jet were eating the stolen food.

Iroh is a big fan of Roast Duck, accepting Song's invitation to her house almost immediately after she mentioned how her mother often makes too much Roast Duck.
