 Notes The amount of schezwan sauce in the recipe can be adjusted to taste. It will also depend on how spicy your schezwan sauce is. My homemade schezwan sauce isn't very spicy so I used 0 to 0 tablespoons of it. You can add more or less depending on how spicy it is and how much flavor of the sauce you prefer in your noodles. If you don't have time to make homemade sauce, just buy your favorite bottle of schezwan sauce from store and use that in the recipe. You can also add more vegetables to these noodles like broccoli, snap peas.
