Combine all the ingredients except for the leaves in a bowl.

Lay 2 leaves shiny side down, on a board with the stem of the leaf pointing towards you.

Spoon approximately 1 tablespoon of the beef mixture onto the bottom half of the leaf.

Work it into a sausage shape, then roll the leaf from bottom to top and place the seam flat on your bench to stop the leaf unrolling, or secure it with a toothpick.

Repeat this process until you have used all of the beef.

Cook the rolls on the barbecue over medium heat, turning to cook, for about 5 minutes, or until done.
