Heat the oil over medium heat. Add the chillies and cook for about a minute or until fragrant. Add the ground beef and saute, breaking up any clumps for about 3-4 minutes or until no pink remains.

Add the fish sauce and stir about another minute.

Remove from the heat and add the onions, zest and juice of the lime and about ½ of the cilantro.

Wash the cabbage, and select smallish, cupping leaves. Spoon the meat mixture into the cabbage cups and sprinkle with the remaining cilantro.
