Slice the flank steak against the grain into thin strips and season evenly with sea salt and black pepper.
In a small glass bowl, whisk together the coconut aminos, raw honey, and toasted sesame oil to create the stir-fry sauce.
Heat the avocado oil in a large skillet or wok over medium-high heat until the oil is shimmering.
Add the beef strips in a single layer and sear for approximately 2 minutes until well-browned, then remove the beef and set it aside on a plate.
Add the broccoli florets, minced garlic, and grated ginger to the same skillet with a splash of water, then cover for 2 minutes to steam-crisp the vegetables.
Return the cooked beef to the skillet, pour in the prepared sauce, and toss everything together for 1 minute until the sauce thickens and coats the ingredients.
Transfer to a plate, garnish with sesame seeds, and serve immediately while hot.
