Cook the egg noodles according to package instructions. Drain and set aside.

In a large skillet, heat the vegetable oil over medium heat. Add the ground beef and cook until browned, breaking apart with a spatula as it cooks. Drain excess fat if necessary.

Once the beef is cooked, stir in the minced garlic and sliced onion. Sauté for about 2-3 minutes until the onion is translucent.

If using bell pepper and broccoli, add them to the skillet and cook for an additional 3-4 minutes until they are tender yet crisp.

In a small bowl, whisk together the soy sauce, hoisin sauce, brown sugar, and ground ginger. Pour this mixture over the beef and vegetables in the skillet.

Add the cooked noodles into the skillet, tossing everything together until the noodles are well coated in the sauce.

Taste and add salt and pepper as needed. Serve hot, garnished with chopped green onions for a fresh pop.
