Slice the flank steak against the grain into thin strips and season with the sea salt and black pepper.
In a small bowl, whisk together the tamari, raw honey, and toasted sesame oil to create the glaze.
Heat the avocado oil in a large skillet or wok over medium-high heat until it begins to shimmer.
Add the beef strips in a single layer and sear for 2 minutes per side until browned and tender.
Remove the beef from the pan and set aside; add the broccoli florets and a splash of water to the same pan.
Cover and steam the broccoli for 3 minutes until bright green and fork-tender.
Stir in the minced garlic and grated ginger, sautéing for 30 seconds until fragrant.
Return the beef to the pan, pour in the prepared glaze, and toss everything together for 1 minute to coat.
Garnish with sesame seeds before serving immediately.
