According to a receipt article on the Monash Low FODMAP blog, majority of the herbs and spices used to make Za'atar are not only gluten free and vegan, but also Low FODMAP. This makes it the perfect seasoning blend to spice up your Low FODMAP meals! For blends purchased in supermarkets or for other separate spice recipes, ensure you review the ingredient list to ensure it's aligned with your dietary requirement. To be on the safe side, my recent recipe for Za'atar is Low FODMAP and contains 4 simple ingredients: Sumac, thyme, sesame seeds and sea salt.
