Slice the flank steak into very thin strips against the grain to ensure maximum tenderness.
In a small bowl, whisk together the tamari, raw honey, grated ginger, minced garlic, and toasted sesame oil to create the glaze.
Heat the avocado oil in a large skillet or wok over medium-high heat until shimmering.
Season the beef strips with sea salt and black pepper, then sear in the hot pan until browned and just cooked through, approximately 3 minutes.
Remove the beef from the pan and set aside, then add the broccoli florets with a tablespoon of water to steam-fry until bright green and tender-crisp.
Return the beef to the pan and pour the sesame-ginger sauce over the mixture, tossing for 1 minute until the sauce thickens and coats every piece.
In a separate small pan, lightly sauté the cauliflower rice for 2-3 minutes until heated through and tender.
Serve the beef and broccoli over the cauliflower rice and garnish with sesame seeds and red pepper flakes for a touch of heat.
