You can add in green onions, sesame seeds or red pepper flakes for additional taste, but this sauce is great on its own too! You can substitute soy sauce or tamari for the coconut aminos. For the oil, you can use avocado oil, peanut oil, olive oil or grapeseed oil instead, but sesame oil has the best flavor. In lieu of corn starch, you can use arrowroot powder or potato starch.
