Place the flank steak in the freezer for 15 minutes to firm up, then slice it very thinly against the grain.
In a small bowl, whisk together the coconut aminos, toasted sesame oil, raw honey, minced ginger, and minced garlic to create the marinade.
Toss the sliced beef with the marinade and let it sit for at least 10 minutes at room temperature.
While the beef marinates, steam the broccoli florets and sliced carrots until they are tender-crisp, about 5 minutes.
Heat a large cast-iron skillet or wok over high heat. Once smoking slightly, add the beef in a single layer, seasoning with sea salt and black pepper.
Sear the beef quickly for 1-2 minutes per side until caramelized and just cooked through.
Arrange the steamed vegetables on a plate, top with the seared beef bulgogi, and garnish with toasted sesame seeds.
