Classic David Lebovitz: Grilled Vegetables with Za’atar Vinaigrette

When I stirred up the dressing to pour over the vegetables, it looked different than usual to me. From the looks of things in the dressing dish, he’d made a vinaigrette, not using the traditional dollop of Dijon mustard, but with my homemade yellow mustard mixed into it. He’d also raided my jar of za’atar, and added some of that as well. I was somewhat surprised, and a little furious, because it wasn’t at all the direction that I had intended for my grilled vegetable to go in.
