Ingredients:

For the Beef:

1 lb beef sirloin, thinly sliced

2 tablespoons soy sauce

1 tablespoon cornstarch

1 tablespoon vegetable oil

For the stir fry veggies

8 oz lo mein noodles or spaghetti noodles pwede

2 tablespoons vegetable oil

1 onion, thinly sliced

2 cloves garlic, minced

1 cup sliced carrots

1 cup sliced bell peppers (red, green, or yellow)

1 cup broccoli florets

1 cup snow peas

¼ cup soy sauce

2 tablespoons oyster sauce

1 teaspoon sesame oil

¼ cup beef broth

1 tablespoon cornstarch mixed with 1 tablespoon water (slurry)

Green onions, chopped (for garnish)

Sesame seeds (optional, for garnish)

Directions:

In a bowl, toss the thinly sliced beef with soy sauce and cornstarch until well coated. Set aside to marinate for about 10-15 minutes.

Cook the lo mein noodles or spaghetti according to the package instructions. Drain and set aside.

Heat 1 tablespoon of vegetable oil in a large skillet or wok over medium-high heat. Add the marinated beef and stir-fry until browned and cooked through, about 4-5 minutes. Remove the beef from the skillet and set aside.

In the same skillet, add the remaining 1 tablespoon of vegetable oil. Sauté the sliced onion, minced garlic, carrots, bell peppers, broccoli, and snow peas until the vegetables are tender-crisp, about 5-7 minutes.

Return the cooked beef to the skillet with the vegetables.

In a small bowl, mix together the soy sauce, oyster sauce, sesame oil, and beef broth. Pour the sauce mixture over the beef and vegetables, stirring to coat evenly.

Add the cornstarch slurry to the skillet and cook for 1-2 minutes, stirring constantly, until the sauce has thickened.

Add the cooked lo mein noodles or spaghetti to the skillet and toss everything together until the noodles are fully coated with the sauce.
