# Step-by-Step Guide:

01 - Combine sliced beef sirloin with soy sauce and cornstarch in a bowl, ensuring the beef is evenly coated. Set aside to marinate for 10 to 15 minutes.
02 - Boil lo mein noodles or spaghetti in a large pot of water according to package instructions, drain thoroughly, and set aside.
03 - Heat 1 tablespoon vegetable oil in a large skillet or wok over medium-high heat. Add marinated beef and stir-fry until browned and just cooked through, approximately 4 to 5 minutes. Remove beef from skillet and reserve.
04 - Add remaining 1 tablespoon vegetable oil to the skillet. Add onion, garlic, carrots, bell peppers, broccoli, and snow peas. Sauté until vegetables are bright and tender-crisp, about 5 to 7 minutes.
05 - Return cooked beef to skillet with vegetables. In a bowl, whisk soy sauce, oyster sauce, sesame oil, and beef broth. Pour sauce into skillet and toss to combine. Stir in cornstarch slurry and cook for 1 to 2 minutes until sauce thickens.
06 - Add cooked noodles to the skillet, tossing to coat thoroughly with sauce and ingredients. Remove from heat, garnish with chopped green onions and sesame seeds if desired, and serve immediately.

# Additional Notes:

01 - Slice beef thinly across the grain to maximize tenderness and quick cooking.
02 - Prepare all vegetables and sauce ingredients in advance for smooth stir-frying.
