Creating Mongolian Ground Beef Noodles is simple if you follow these easy steps:

1. Cook the Noodles: In a large pot, bring water to a boil. Add the egg noodles and cook according to package instructions until al dente. Drain and set aside.
2. Brown the Beef: In a large skillet or wok, heat the vegetable oil over medium-high heat. Add the ground beef and cook until browned, breaking it apart with a spatula.

4. Stir in the Sauce: Add the soy sauce, oyster sauce, hoisin sauce, and brown sugar to the skillet. Mix well to coat the beef.
5. Add Vegetables: Incorporate the broccoli florets and sliced bell pepper into the skillet. Stir-fry for an additional 3-4 minutes until the vegetables are tender-crisp.
6. Combine with Noodles: Add the cooked noodles to the skillet and toss everything together, ensuring the noodles are well coated with the sauce.
7. Season: Taste and adjust seasoning with salt and pepper as needed.
8. Garnish: Remove from heat and sprinkle with chopped green onions and sesame seeds if desired.
