Slice the flank steak against the grain into thin strips and season with sea salt and black pepper.
In a small bowl, whisk together the coconut aminos, honey, minced garlic, and grated ginger.
Heat the toasted sesame oil in a large skillet or wok over medium-high heat.
Add the beef to the skillet and sear until browned, approximately 2-3 minutes, then remove and set aside.
Add the broccoli florets to the same skillet with a splash of water, covering for 2 minutes to steam until tender-crisp.
Return the beef to the skillet, pour in the sauce, and toss everything together for 1 minute until the sauce thickens and coats the ingredients.
Transfer to a plate and garnish with sesame seeds before serving.
