Add the tahini, soy sauce, sweet chili sauce, garlic, ginger and bouillon to a jar. Whisk until a sauce is formed.
Then add the rest of the ingredients in the order they are listed. Refrigerate until you want to use. Before adding hot water, allow the jar to cool to room temperature to avoid breakage.
Pour in hot water until almost full, then allow to sit for 5 to 8 minutes, until the noodles are soft. Enjoy immediately, or transfer to a bowl if desired.
