- 1 medium onion, thinly sliced
- 2 tbsp vegetable oil
- For the Sauce:
- 1/4 cup soy sauce
- 2 tbsp oyster sauce
- 1 tbsp cornstarch

- 1 tbsp rice vinegar
- 1 tbsp honey or brown sugar
- 2 cloves garlic, minced
- 1 tsp grated fresh ginger
- 1 tsp sesame oil
- Optional: 1/2 tsp red pepper flakes for heat
Directions
- Make the Sauce: In a small bowl, whisk together soy sauce, oyster sauce, cornstarch, water, rice vinegar, honey, garlic, ginger, sesame oil, and red pepper flakes (if using). Set aside.
- Cook the Steak: Heat 1 tbsp vegetable oil in a large skillet or wok over medium-high heat. Add the beef strips and stir-fry for 2-3 minutes until browned and cooked through. Remove the beef and set aside.
- Cook the Vegetables: In the same skillet, add the remaining oil and stir-fry the bell peppers and onions for 4-5 minutes, until they’re tender but still crisp.
- Combine and Sauce: Return the cooked beef to the skillet and pour in the prepared sauce. Stir everything together to coat evenly. Cook for an additional 2-3 minutes until the sauce thickens.
- Serve: Remove from heat and serve hot over steamed rice or noodles. Garnish with sesame seeds or chopped green onions if desired.
