Let salmon marinate in a deep bowl for 10 minutes with sesame oil, avocado oil, coconut aminos, pink salt and sesame seeds. Flip twice.
Cover a sheet pan with parchment paper or foil and lay the salmon flat, skin down, one half of the pan and pour the rest of the marinade over the top.
Slice the ends off bok choy, then again lengthwise. Spray with avocado oil & season with pink salt + ground pepper. Add to sheet pan and broil in the oven, center rack, 500 degrees F for about 10 minutes, or until bok choy starts to char on the ends.
