1. In a small bowl, whisk together soy sauce, oyster sauce, cornstarch, water, rice vinegar, honey, minced garlic, grated ginger, sesame oil, and red pepper flakes if using. Set aside.

3. Add the remaining tablespoon of oil to the skillet. Stir-fry the bell peppers and onion for 4โ5 minutes until tender but still crisp.
