Za'atar is easy to make at home from scratch with just four ingredients. While in Lebanon wild thyme is used, regular thyme from the supermarket or your garden makes a fine substitute. Za'atar refers both to the thyme plant itself, as well as this spice mix.
For a simple and delicious way to use za'atar, sprinkle the spice mixture over a plate of labneh and drizzle with olive oil. Serve with pitta bread as a dip.
