Looks yummy!! This recipe is especially popular in the Agrinion area (NW Greece). It uses a version of Avgolemono soup as a sauce for the meatballs or keftedes. I am leaving the metric measures so the recipe is exactly as I found it. The site does not state how many it serves or what the time is for prep, so I am guessing here. I am also assuming that minced beef is the same as ground beef in the U.S. From realgreekrecipes.blogspot.com. Posted for ZWT6.
