Preheat oven to 425ºF. Line a rimmed baking sheet with parchment paper.
Arrange salmon on sheet pan with green beans around it. Drizzle oil over green beans and sprinkle green beans and salmon with salt and pepper.
Spread teriyaki sauce, about 2 tablespoons per fillet, over salmon. Bake until salmon easily flakes with a fork, about 15 minutes. Remove from oven and drizzle with additional teriyaki sauce, if desired.
