Thinly slice the flank steak against the grain into bite-sized strips and season with sea salt and black pepper.
In a small bowl, whisk together the tamari, toasted sesame oil, grated fresh ginger, minced garlic, and raw honey until well combined.
Heat one teaspoon of avocado oil in a large skillet or wok over high heat until shimmering.
Add the beef strips in a single layer and sear for 2 minutes until browned and caramelized, then remove from the pan and set aside.
Add the remaining teaspoon of avocado oil and the broccoli florets to the same pan with one tablespoon of water, covering with a lid for 2 minutes to steam-tenderize.
Remove the lid, return the beef to the pan, and pour the sesame-ginger sauce over the mixture.
Toss everything together for 1-2 minutes until the sauce thickens and coats the beef and broccoli beautifully.
Garnish with sesame seeds before serving hot.
