Begin by slicing the beef flank steak into thin, even strips about ¼ inch thick.

In a bowl, combine the sliced beef with low-sodium soy sauce, minced garlic, grated ginger, and cornstarch. Allow it to marinate for 15 minutes.

Warm up a large skillet over medium-high heat and drizzle in the sesame oil. Once hot, add the marinated beef in a single layer and cook for about 3 minutes until browned.

Toss in the broccoli florets to the skillet and stir-fry with the beef for an additional 3 minutes until the broccoli is tender-crisp.

Pour in the low-sodium beef broth, stirring well to blend the flavors together. Let it simmer for a minute.

Plate your Beef and Broccoli hot, optionally served over rice or noodles.
