Thinly slice the flank steak against the grain into bite-sized strips.
In a small bowl, whisk together the coconut aminos, toasted sesame oil, honey, grated ginger, and minced garlic to create the marinade.
Place the beef in a bowl and toss with half of the marinade, sea salt, and black pepper; let it sit for 10 minutes.
Steam the broccoli florets and sliced carrots until tender-crisp, about 4-5 minutes.
In a separate pan over medium heat, sauté the cauliflower rice for 3-4 minutes until warmed through and slightly softened.
Heat a large skillet or wok over high heat. Add the beef in a single layer and sear for 2 minutes per side until browned and caramelized.
Pour the remaining marinade over the beef and toss for 30 seconds until the sauce thickens and coats the meat.
Serve the beef over the cauliflower rice and steamed vegetables, garnishing with sesame seeds and sliced green onions.
