Pre-heat over to 400 degrees.
Line a baking sheet with parchment paper.
Rinse salmon with cold water and pat dry with a paper towel.
Place salmon on baking tray and season with onion powder, garlic powder and pepper.
Roast salmon in over for 15 minutes.
While salmon is roasting place all ingredients for the sauce in a blender or food processor: mayo, dijon mustard, garlic, siracha, coconut aminos, rice vinegar, honey, and seasme oil. Blend until emulsified.
When timer beeps on the over remove salmon and pour the sauce over the salmon.
Sprinkle with sesame seeds and return to over for 15 minutes. *Optional: at 13 minutes, you can turn the over off and set to broil for 2-4 minutes to lightly crisp the top. Make sure you watch it closely.
Remove from over and top with freshly chopped cilantro.
It's great served with cooked vegetables and/or jasmine rice!
