This is the burger version of the (very popular) Spanakopita meatballs.
Big difference; the burger is raw and the meatballs are fully cooked but it’s the same ingredients for both.
Noteworthy- there are bread crumbs in the burger so these should not be served on a roll. Serve them with a salad and/or your favorite potato/rice/veg.
Like the meatballs a nice Tzatziki sauce or a plain Greek Yogurt would be perfect.
One of my favorites to eat at home!
