Finely mince the onion and herbs together. Transfer to a bowl with the beef, spices and salt to taste and mix thoroughly.
Form into 24 balls each about 4 cm (1½ inches) across, then flatten slightly and thread onto 6 skewers, four to a skewer. (You can also flatten them completely to form small burgers.)
Cook for 5 minutes, turning regularly, over hot coals or under a hot grill.
Serve with a chopped, mixed salad.
