Za'atar, a Middle Eastern spice mixture most often made with sumac (a tart spice), sesame seeds, thyme, and oregano, gets a new starring role as a flavor for homemade popcorn. Best of all, it's incredibly easy: just sprinkle store-bought za-atar on the freshly popped corn and you're all set.
Place popped popcorn in a large mixing bowl and drizzle olive all over, tossing to coat evenly. Add za'atar, tossing to coat evenly. Season with salt and serve. Popcorn can be stored at room temperature in a zipper-lock bag overnight.
