Preheat the Oven: Preheat your oven to 400°F (200°C).
Prepare the Honey Garlic Sauce: In a small bowl, whisk together honey, soy sauce, minced garlic, and olive oil until well combined.
Arrange the Ingredients: On a large sheet pan, place the halved baby potatoes. Drizzle with half of the honey garlic sauce, season with salt and pepper, and toss to coat. Spread the potatoes out in a single layer.
Roast the Potatoes: Roast the baby potatoes in the preheated oven for 15 minutes.
Add Salmon and Green Beans: After 15 minutes, remove the sheet pan from the oven. Push the potatoes to the sides of the pan, and add the salmon fillets in the center. Place the green beans on the other side. Drizzle the remaining honey garlic sauce over the salmon and green beans.
Continue Cooking: Return the sheet pan to the oven and roast for an additional 12-15 minutes, or until the salmon flakes easily with a fork and the vegetables are tender.
Serve: Garnish with sesame seeds and chopped green onions if desired. Serve hot and enjoy!
