In a large skillet, brown the ground beef. Break up the beef as it browns. Then drain off any excess grease. Add in the garlic and ginger and cook for 1 minute until the garlic is aromatic.
While the beef is cooking, prepare the noodles based on the package instructions. Rinse with cold water and set aside.
Add the soy sauce, beef broth, brown sugar, hoisin sauce, pepper and red pepper flakes to the skillet with the beef. Stir to combine all the ingredients.
Mix the cornstarch with a small amount of cold water. Stir until it’s dissolved and then stir this mixture into the skillet as well. Bring to a low boil. Heat until the sauce has thickened and then stir in the cooked noodles. Toss to combine the noodles thoroughly with the sauce and the meat mixture.
Remove the pan from the heat but allow the noodles to sit in the sauce mixture for a few minutes to absorb the flavors. Then serve warm topped with the sliced green onions and sesame seeds. Enjoy!
