03 - 1 tablespoon soy sauce

→ Vegetables

04 - 1 red bell pepper, julienned

# How to Make It:

01 - In a bowl, combine the thinly sliced beef strips with cornstarch and 1 tablespoon of soy sauce. Allow to marinate for 10 minutes.
02 - In a separate small bowl, whisk together the soy sauce, oyster sauce, rice vinegar, chili garlic sauce, sesame oil, and brown sugar until thoroughly combined.
03 - Heat 1 tablespoon of a neutral cooking oil in a large wok or skillet over high heat. Add the marinated beef and stir-fry for 2–3 minutes until it develops a browned exterior but is not fully cooked through. Remove the beef from the wok and set aside.
04 - Add an additional 1 tablespoon of oil to the wok. Introduce the sliced onion, minced garlic, and minced ginger, stir-frying for 1 minute until fragrant.
05 - Incorporate the julienned bell peppers and trimmed snow peas into the wok; continue to stir-fry for 2–3 minutes until the vegetables are tender-crisp.
06 - Return the seared beef to the wok. Pour the prepared sauce over all ingredients and toss vigorously to ensure even coating.
07 - Continue to stir-fry for an additional 2–3 minutes, allowing the beef to cook completely and the sauce to slightly thicken.
08 - Prior to serving, garnish with freshly sliced spring onions and toasted sesame seeds.
