Pat the salmon fillet dry with a paper towel and season both sides with sea salt and black pepper.
In a small bowl, whisk together the tamari, honey, grated fresh ginger, and minced garlic until the honey is fully dissolved.
Heat the toasted sesame oil in a medium non-stick skillet over medium-high heat until it begins to shimmer.
Place the salmon in the skillet skin-side up and sear for 4 to 5 minutes until a deep golden crust forms on the surface.
Flip the salmon carefully and pour the tamari mixture into the pan, allowing it to bubble and reduce into a thick glaze for 3 minutes.
While the salmon finishes, steam the broccoli florets in a steamer basket over boiling water for 4 minutes until bright green and tender.
Transfer the salmon to a plate, drizzle with the remaining pan glaze, and serve alongside the steamed broccoli topped with sesame seeds.
