For best results prepare this one-day ahead. When the ingredients are allowed to blend overnight the flavour is amazing. An incredible soup that can be a meal on its own. Be prepared; all the chopping takes time if you are doing it by hand. I cheat by running the vegetables through the food processor twice.
These meatballs are very different because of the texture created after mixing in the food processor. I usually use a homemade tomato sauce but a good store bought sauce will work fine as well (Tomato & Basil). Top meatballs with sauce and mozzarella cheese and let your taste buds delight. Even Nona says she loves them.
I find these burgers need no additional condiments. Recipe can be doubled, and burgers can be frozen for a week or so. If you can, allow these burgers to sit in the fridge for up to 8 hours for the flavours to really come together.
My Grandmother (Teta) made this dish as an accompaniment to Chicken, Pork, or Lamb dishes. My son will make a meal out of it on its own. The yogurt and pine nuts really enhance the flavour, but are optional. To truly enjoy this I would not recommend using ground beef. It also very easily reheats and can be frozen as well.
