Additions and SubstitutionsIn addition to the butter, you can add a teaspoon of toasted sesame oil for extra flavor.I used a store bought stir-fry sauce, but you could add in some oyster sauce, fish sauce, or hoisin sauce. If you don't have honey, you can use brown sugar, maple syrup, or agave nectar.Dietary ModificationsThis recipe is meatless, just be sure you use a vegetarian stir fry sauce for a vegetarian option.Use plant-based butter, noodles, and sauce for a vegan option.Use thick rice noodles for a gluten free noodle option. Make sure any sauce ingredients (like stir fry sauce or soy sauce) are certified gluten free as well.
