Slice the flank steak against the grain into thin, bite-sized strips and season with sea salt and black pepper.
In a small bowl, whisk together the coconut aminos, honey, grated ginger, and minced garlic to create the teriyaki glaze.
Heat a large skillet or wok over medium-high heat with half of the sesame oil.
Add the broccoli florets and a splash of water, covering for 2 minutes to steam until bright green and tender-crisp.
Remove the broccoli from the pan, add the remaining sesame oil, and sear the beef strips for 2-3 minutes until browned.
Return the broccoli to the pan and pour in the teriyaki glaze, tossing for 1 minute until the sauce thickens slightly and coats the ingredients.
In a separate small pan, lightly sauté the cauliflower rice for 3-4 minutes until warmed through and slightly softened.
Serve the beef and broccoli over the cauliflower rice and garnish with sesame seeds.
