We begin making the sauce by adding all the ingredients in a blender, mixing well but not as a fine cream. Keep refrigerated.
In a large bowl add the breadcrumbs along with the onion, oil, mustard, sumac, turmeric, paprika, parsley, eggs, mint, salt and pepper and pour over them the wine. Mix thoroughly and then add the minced chicken meat, combine well, cover with plastic film and refrigerate for an hour or even overnight.
Next day, or an hour later, turn the oven with the upper and down elements on and the air on as well, not the grill, to 200° Celsius and place a grill in the middle of the oven.
In the meantime, take the mixture from the refrigerator and while cold form into golf size balls, slightly pressed and placed on a lightly oiled oven proof dish. Brush all over them some olive oil, cover with aluminium foil and cook for 15 minutes. Flip on the other side and cook for 9 minutes more. You want a golden colour for your burgers, and the inside cooked but juicy too!
Serve with the feta sauce along with either quinoa or French fries and seasonal green salad.
