Mix all the sauce ingredients in a small bowl and set aside.
Next, prepare the beef, season it with salt, cut the broccoli into florets, and set them aside.
Heat a large pan over medium-high heat with a drizzle of oil.
When hot, add the broccoli florets and cook until crisp and tender. Then, remove from the pan to a plate.
Then, add a little more olive oil and the beef strips and stir-fry for 5 minutes or until cooked.
Next, reduce the heat to low and add the sauce mixture. Mix everything together until the sauce starts to thicken.
Next, add the broccoli florets back to the pan and mix to combine everything.
Garnish with sesame seeds on top, and serve with white basmati rice!
