In a small bowl, whisk together the soy sauce, sesame oil, ginger, red pepper flakes, and honey until well combined. Set aside.
Slice the flank steak into thin strips against the grain.
Heat a large skillet or wok over medium-high heat. Add a small amount of oil if needed, then add the beef. Sear for 2–3 minutes per side until browned and cooked through. Remove from the pan and set aside.
Steam the broccoli until tender but still crisp, about 3–5 minutes.
Add the steamed broccoli to the skillet, then return the cooked beef to the pan.
Pour the sauce over the beef and broccoli, tossing everything together to coat evenly. Let cook for an additional 1–2 minutes until heated through.
Serve immediately and enjoy!
