01 - Combine sliced beef with soy sauce, cornstarch, sherry, and sesame oil in a bowl. Mix thoroughly and allow to marinate for 10 minutes.
02 - Whisk together soy sauce, oyster sauce, hoisin sauce, honey, water, and cornstarch in a separate bowl until smooth. Set aside.
03 - Heat 1 tablespoon of vegetable oil in a large wok or skillet over high heat. Stir-fry the marinated beef for 2 to 3 minutes until browned and just cooked through. Remove and set aside.
04 - Add remaining oil to the wok. Stir-fry garlic, ginger, and spring onions for 30 seconds until fragrant.
05 - Add broccoli florets and julienned carrots to the wok, stirring for 2 minutes. Incorporate sliced bell peppers and continue stir-frying for an additional 2 minutes until vegetables are crisp-tender.
06 - Return cooked beef to the wok. Pour in the prepared sauce and toss everything together. Cook for 1 to 2 minutes until the sauce thickens and evenly coats the beef and vegetables.
07 - Serve immediately, optionally garnished with additional spring onions or sesame seeds. Ideal accompanied by steamed rice or noodles.
