Real Italian/Sicilian Meat Balls.

[Worth1]

I am going to have spaghetti and meat balls for new years dinner.
I have heard a thousand ideas on what a real meatball is.
Some with pork veal and beef.
Some with beef and lamb.
Some pork and beef and some with just beef.
Then there is the spices that go in them.
I have even seen arguments break out about them.
In your opinion what is a real (Real Italian/Sicilian Meat Ball) or is there such a thing?
