In a small mixing bowl, prepare your sauce. Whisk together the soy sauce, hoisin sauce, brown sugar, beef broth, ginger, red pepper flakes, and black pepper. Set aside.
In a large saucepan, boil your noodles according to package directions.
In a large deep saute pan, brown the hamburger meat until no longer pink.
Pour the sauce into the meat. Give it a good stir and simmer for 10 minutes stirring occasionally.
When the noodles are done, drain the water then pour the noodles into the beef sauce mixture. Stir well to coat all the noodles. Let sit for a few minutes to allow the noodles to soak up all the sauce.
Garnish with diced green onions and toasted sesame seeds. Enjoy!
