Place all the ingredients for the sauce into a small pot. Over medium heat, cook the sauce on a low boil. Using a wooden spoon, stir the liquid until the sugar melts. Once melted, remove from heat and let cool. Once cool, pour the sauce into a container and store in the refrigerator until ready to use. This can be made a day ahead.
Cook the egg noodles in boiling water. For fresh egg noodles, which I use, boil for about 4 minutes. You can taste a noodle to check for doneness. When cooked, strain the noodles in a colander and run cold water on it. The noodles can then be placed in the refrigerator until ready to use. This can be made a day ahead.
When ready to serve, transfer the noodles into a large bowl and pour the sauce over the noodles. Add the bbq pork, sesame seeds, green onions, and cilantro. Mix well.
