Keftedakia, the mini burgers :)

Do you remember my home-burgers?
With the same recipe, you can make mini-burgers that you fry in a big frying-pan with good olive-oil and in greek we call them keftedakia that stands for meatballs :)
It is great for a buffet and kids and adults get crazy with them. So crazy, that I did not manage to get a photo from mine when done as they disappeared immediately!   
[updated] I managed to do again in order to show you the result...
