• 1 red bell pepper, thinly sliced
• 1 green bell pepper, thinly sliced
• 1 medium onion, thinly sliced
• 2 tbsp soy sauce
• 1 tbsp oyster sauce (optional)
• 1 tbsp hoisin sauce
• 1 tbsp cornstarch
• 1 tbsp sesame oil (or vegetable oil)
• 2 cloves garlic, minced
• 1 tsp grated fresh ginger (optional)
• 1 tbsp rice vinegar or lime juice (optional for brightness)

Instructions

1. Marinate the Beef:
   • In a bowl, combine the sliced beef with soy sauce, hoisin sauce, cornstarch, and a pinch of pepper.
   • Mix well and let marinate for 15–30 minutes.
2. Prep Your Veggies:

3. Stir-Fry Time:
   • Heat a large pan or wok over medium-high heat. Add half the oil.

   • Add garlic and ginger, stir for 30 seconds.
   • Add bell peppers and stir-fry until just tender (about 3–4 minutes).
5. Bring it Together:
   • Return beef to the pan. Add oyster sauce and rice vinegar if using.
   • Toss everything together and cook for another 1–2 minutes to blend flavors.
6. Serve:
   • Spoon over steamed rice or noodles.
   • Garnish with chopped green onions and sesame seeds if desired.
