Preheat your oven to 400°F (200°C).
Prepare the marinade by whisking together honey, soy sauce, Dijon mustard, olive oil, garlic powder, salt, and pepper in a bowl.
In a large baking tray, add the halved or quartered potatoes and drizzle with a bit of olive oil, salt, and pepper. Toss to coat.
Spread the potatoes out in a single layer and put them in the preheated oven. Roast for 15 minutes.
After 15 minutes, remove the tray from the oven. Place the salmon fillets skin-side down on top of the potatoes.
Drizzle the prepared marinade evenly over the salmon fillets and potatoes.
Return the tray to the oven and roast for an additional 15-20 minutes, or until the salmon flakes easily with a fork.
Remove from the oven and let rest for a few minutes. Garnish with fresh parsley, if desired.
