Cut onion and beef into thin strips (beef should be bite size).

Heat a pan or wok over high heat.

Add 2 tablespoons of oil to the hot pan or wok.

When the oil is hot and shimmering, add minced garlic and onion.

Cook for about 2 minutes, or until the onion is lightly browned.

Add broccoli florets to the pan and cook for another 2 minutes.

Add the sirloin to the pan and stir-fry until cooked through.

Be careful not to overcook, or the broccoli florets will become mushy.

While the beef and broccoli are cooking, combine cooking sherry, cornstarch, and soy sauce in a small bowl.

Turn off the heat under the pan.

Drizzle honey all over the stir-fry.

Add the soy sauce mixture to the pan and stir to coat.

Stir in crushed red pepper flakes to taste.

Serve immediately.
