In a small bowl, whisk together the teriyaki sauce, olive oil, grated ginger, minced garlic, salt, and pepper.
Place the salmon fillets on a large sheet pan lined with parchment paper. Sprinkle the salmon with salt and pepper, then brush generously with the teriyaki sauce mixture.
In a mixing bowl, combine the broccoli, sliced bell peppers, and snap peas. Drizzle with a little olive oil, and season with salt and pepper. Toss until well coated.
Arrange the vegetable mixture around the salmon on the sheet pan. Drizzle any remaining teriyaki sauce over the veggies.
Bake in the preheated oven for 15-20 minutes, or until the salmon is cooked through and flakes easily with a fork.
Remove from the oven and let cool slightly. Garnish with sesame seeds and chopped green onions before serving.
Notes
Serve directly from the sheet pan for a rustic feel, or plate each salmon fillet with a colorful assortment of veggies.
