Divide the ground beef into two equal portions. Heat the vegetable oil in a pan and add the diced onions and saute for couple of minutes until onions changes it color and soften. 

Add the first half of the ground beef to the pan and saute it with onions at medium-high heat about 6 minutes. Then take the pan a side and let it to cool down.

Knead the cooled down onion and ground beef mixture with the remaining half portion ground beef in the bowl and add 1 egg, salt, red pepper, black pepper,boiled rice and finely chopped parsley and mix all.

Spread the flour on a flat plate and put a small cup of water aside to help shaping the meat balls. Beat the remaining 3 eggs into another cup for dipping the meatballs.

Shape the meatballs as big as an egg size in your palm. Make them oval shape but not too thick. Medium size thickness is fine. 

After you finish shaping the meatballs; first put the meatball to the flour and then dip the floured meatball into the beaten eggs and then shallow fry about 3-5 minutes each side of the meatball until they become crispy and golden color.
