Preheat the oven to 400°F (205°C) and line a baking pan with baking paper.
To make the glaze take a bowl and whisk the soy sauce, rice vinegar, powdered Erythritol, sesame oil, garlic powder, and ground ginger.
Using a brush, glaze the salmon fillets.
Slice the pepper and arrange on the baking sheet with the green beans. Drizzle with avocado oil and season with salt. Bake in the oven for about 10 minutes.
Add the salmon fillets to the baking tray and give them a final glaze. Sprinkle the fillets with sesame seeds and optionally drizzle the green beans and peppers with any leftover glaze.
Return to the oven for about 10-12 more minutes, until the salmon is cooked through and serve hot.
