When consuming a gluten-free diet, it's necessary to check all listing on each ingredient to ensure it's aligned with your nutritional restrictions.  The key ingredients to look out for are: Noodles - Although vermicelli noodles are traditionally gluten-free, many brands include gluten as a filler. Be sure to purchase a gluten-free brand or one without gluten ingredients. Soy Sauce - Surprisingly most soy sauce brands contain gluten. If you're mindful of your gluten intake, Tamari sauce is a perfect alternative.
