Prepare the Sauce:
In a small bowl, whisk together soy sauce, oyster sauce, cornstarch, water, honey, rice vinegar, sesame oil, and red pepper flakes. Set aside.
Cook the Broccoli:
Heat 1 tbsp of vegetable oil in a large skillet or wok over medium-high heat. Add the broccoli florets and 1/4 cup of water. Cook, stirring occasionally, until the broccoli is tender but still crisp, about 3-4 minutes. Remove from the skillet and set aside.
Cook the Shrimp:
In the same skillet, heat the remaining 1 tbsp of vegetable oil. Add the minced garlic and ginger, and cook for about 30 seconds until fragrant.
Add the shrimp to the skillet and cook until they are pink and opaque, about 2-3 minutes per side.
Combine Everything:
Return the cooked broccoli to the skillet with the shrimp. Pour the sauce over the shrimp and broccoli, stirring to coat everything evenly. Cook for an additional 2-3 minutes until the sauce has thickened and everything is heated through.
Serve:
Garnish with sesame seeds and sliced green onions. Serve the Shrimp and Broccoli Stir-Fry hot over steamed rice or noodles.
