It is best to grind your own 2 lbs (1 kilogram) of beef mince. Mix in the very finely chopped 2 types of onions, parsley, eggs and all the spices. Allow the meat to cool for 30-40 minutes in the refrigerator.
Then, with greased hands, make flat meatballs and put them on a preheated grill. Optionally, you can roll them in flour a little before frying. Some people prefer not to put eggs in their meatballs, but to me they taste perfect with them.
