* Use a little less salt if your za’atar is seasoned.
** If you’re in a hurry, you can get away with marinating it for 30 minutes, but the flavor intensifies if you leave it a bit longer. If you marinade for a shorter period, glaze the lamb with a little extra molasses during the grilling.
*** If you’re making everything ahead of time: Simply mix the veggies with the seasoning, skewer them immediately, and refrigerate for up to a day. Start the lamb off by marinating it in a ziplock bag for an hour, then skewer and refrigerate for up to a day.
