Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Finely chop or process the pistachios until they form a coarse meal. Set aside.
Pat the salmon fillet dry with paper towels. Season lightly with salt and pepper if desired.
Brush the top side of the salmon generously with a little low-sodium soy sauce.
Press the chopped pistachios onto the top of the salmon so they adhere well.
Place the salmon, pistachio side up, on the prepared baking sheet.
Bake in the preheated oven for 12-15 minutes until the salmon is just cooked through and the pistachio crust is crisp.
While the salmon bakes, combine fresh orange juice, grated ginger, the remaining soy sauce, and honey in a small saucepan.
Heat the mixture over medium heat, stirring frequently until it slightly thickens into a glaze, about 3-5 minutes.
Once the salmon is done, drizzle the citrus-ginger glaze over the top.
Serve immediately, enjoying the combination of nutty crunch and vibrant, tangy flavor.
