Grilled Za’atar Chicken Pitas

Za’atar is a mixture of sumac, dried thyme, salt, toasted sesame seeds and sometimes dried savory, marjoram or oregano. The dominate taste comes from the sumac though; a tart, earthy spice that goes well baked on a pita, on poultry or in dressings. By using non-fat — but still thick — Greek yogurt you keep down the level of fat in your marinade, (unlike what I call “special chicken” which calls for a fair amount of butter) while still adding a lot of tang and richness to meat. It also makes for a nice char when you put the skewers over the fire. Lemon zest and garlic make it a party.
