1) Mix together all the ingredients until well blended. Divide into 6 balls, and then roll each ball on a board with a cupped hand to turn them into ovals.
2) Thread onto 4 metal skewers and brush with oil.
3) To cook on a griddle: heat the pan until you can feel a good heat rising and cook for 3-4 mins each side. Don't turn until they are well sealed or the meat will stick to the grill or pan.
4) Serve with a dipping sauce.
