Instructions:
1. Marinate the Beef:
- In a large bowl, toss the sliced beef with 2 tbsp soy sauce, 2 tbsp cornstarch, 1 tbsp oil, Shaoxing wine, and baking soda if using.
 - Let it marinate for at least 20 minutes (up to 1 hour in the fridge).
 
2. Make the Sauce:
- In a bowl or measuring cup, whisk together soy sauce, oyster sauce, hoisin, broth, brown sugar, sesame oil, vinegar, black pepper, and cornstarch. Set aside.
 
3. Stir-Fry in Batches:
- Heat 1–2 tbsp oil in a large wok or skillet over high heat.
 - Add beef in batches (don’t overcrowd) and sear until browned, about 2–3 minutes per batch. Remove to a clean bowl or plate.
 
4. Cook the Veggies:
- Add a bit more oil to the wok. Stir-fry onions and bell peppers until slightly tender but still crisp (about 4–5 minutes).
 - Add garlic and ginger, stir-fry for another 30 seconds until fragrant.
 
5. Combine Everything:
- Return the beef to the wok with the veggies.
 - Pour in the sauce and stir well. Let it cook for 2–3 minutes until the sauce thickens and everything is well coated.
