Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.
Place the salmon fillet on the prepared baking sheet. Drizzle with olive oil and season with garlic powder, onion powder, paprika, salt, and pepper.
Bake the salmon in the preheated oven for 12-15 minutes, or until it flakes easily with a fork.
While the salmon is baking, prepare the rice according to package instructions if not already cooked.
Steam the broccoli florets until tender, about 5-7 minutes.
Once the salmon is done, remove it from the oven and let it rest for a few minutes.
Fluff the rice and divide it into bowls. Top each bowl with pieces of salmon, steamed broccoli, avocado slices, and chopped green onions.
Drizzle soy sauce over the top and sprinkle with sesame seeds before serving.
