Using the stovetop and a medium skillet with high sides, brown the ground beef, ginger and garlic until beef is cooked through.
Use the back of a wooden spoon to make sure meat is well broken up.
Drain excess fat and return the pan to the stovetop.
While the ground beef is cooking, get a pot of water started for the pasta noodles; salt the water well so that the noodles soak up that flavor.
In a small dish, combine the soy sauce, beef broth, brown sugar, red pepper flakes, pepper and hoisin sauce; pour into ground beef mixture.
Sauté in the pan for about 3 minutes to allow the ground beef to absorb the flavors.
Once the pasta is done cooking, transfer the noodles to the ground beef mixture.
Mix thoroughly and allow to cook for a couple minutes more to allow the sauce to thicken.
Remove from the stovetop; top with green onions and toasted sesame seeds.
