To prepare Mongolian Ground Beef Noodles, follow these straightforward steps:

1. Cook the Noodles: Bring a large pot of salted water to a boil. Cook the egg noodles according to package instructions until al dente. Drain and set aside.

2. Heat Oil: In a large skillet or wok, heat the vegetable oil over medium-high heat.

3. Brown the Beef: Add the ground beef to the skillet. Cook until browned, breaking it into small pieces with a spatula, about 5-7 minutes.

4. Add Vegetables: Stir in the chopped bell peppers, onions, and garlic. Sauté until the vegetables begin to soften, about 3-4 minutes.

5. Add Broccoli: Toss in the broccoli florets, cooking for an additional 3 minutes until tender but still vibrant.

6. Make the Sauce: In a small bowl, mix the soy sauce, oyster sauce, hoisin sauce, sesame oil, salt, and pepper.

7. Combine: Pour the sauce over the beef and vegetables in the skillet. Stir well to coat everything evenly.

8. Add Noodles: Gently fold the cooked noodles into the skillet, tossing until everything is combined and heated through.

9. Final Adjustments: Taste and adjust seasoning, adding more soy sauce if desired.

10. Serve: Remove from heat. Garnish with chopped green onions before serving.

By following these steps, you’ll create an eye-catching dish that’s delicious and satisfying.
