In a small bowl, whisk together the tamari, honey, grated fresh ginger, minced garlic, toasted sesame oil, and rice vinegar to create the glaze.
Heat a non-stick skillet over medium-high heat. Once hot, place the salmon fillet in the pan skin-side down.
Sear the salmon for 4 to 5 minutes until the skin is crispy and golden, then carefully flip the fillet.
Pour the prepared glaze into the skillet. Let it bubble and reduce for 2 to 3 minutes, frequently spooning the thickening sauce over the salmon.
While the salmon finishes, steam the broccoli florets in a steamer basket over boiling water for 4 to 5 minutes until bright green and crisp-tender.
Transfer the salmon and broccoli to a plate, drizzling any remaining glaze from the pan over the top.
Garnish the dish with sliced green onions and sesame seeds before serving.
