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, toasted sesame oil, minced ginger, and minced garlic to create the stir-fry glaze.
Heat the avocado oil in a large stainless steel skillet or wok over high heat until it begins to shimmer.
Add the beef strips in a single layer and sear undisturbed for 2 minutes until a deep brown crust forms, then remove the beef from the pan and set aside.
Add the broccoli florets to the same pan with two tablespoons of water, immediately covering with a lid for 2 minutes to steam-cook until they are bright green and tender-crisp.
Remove the lid and return the beef to the pan, then pour the prepared glaze over the mixture.
Toss everything constantly for 60 seconds until the sauce reduces into a thick, glossy coating.
Transfer to a plate, garnish with sesame seeds, and enjoy immediately while hot.
