Grill the koftas on a medium high heat grill, about 350 degrees, for 3 minutes per side, or until
an internal read thermometer (I recommend the Thermapen) reads 160 degrees. Make sure you oil your grill grates so the meat does not stick. After you pull them off, let them rest under foil for 10 minutes. Meanwhile, grill your pita flat bread for a few minutes to get warm. Serve the koftas with the warm pita bread and greek yogurt dipping sauce. Use chopped mint as a garnish before serving if you like.
