Preheat oven to 400° Fahrenheit, line a baking sheet with parchment paper.
Make sauce by whisking all sauce ingredients in a bowl or jar. Set aside.
Place salmon fillets on baking sheet and season liberally with salt and pepper. Place in the oven to bake for 15-20 until flaky with a fork. Cooking time will vary depending on the size of your fillets.
While the salmon is baking, prep cauliflower, broccoli, bell pepper and green onion as noted.
When the salmon has about 5 minutes left, place oil and all of the veggies (except reserve half the green onion for a garnish) in a large skillet over medium heat. Cook stirring occasionally until salmon is done. Season with salt and pepper, to taste.
Once salmon is done, remove from oven and make bowls. Start with a couple scoops of the veggie mixture, add salmon, drizzle sauce over everything and top with sesame seeds and the remaining green onion. Enjoy!
