Turn your broiler on and place a rack 5 inches beneath. Line a sheet tray with foil and spray the sheet tray with oil. Place salmon on the foil.
Lightly season your salmon with salt. In a bowl, whisk together the miso, maple syrup, lime juice, and coconut aminos. With a culinary brush, brush the mixture onto your salmon.
Place salmon under the broiler for 3 minutes. After the 3 minutes, remove from the oven and brush one more time with the mixture. Place back in the oven and set another timer for 5 minutes. After 5 minutes, check your salmon to make sure it is not getting to dark. If it is getting too dark, move to a lower shelf and cook for another 2-5 minutes, until an internal thermometer reads 125*F, or until it is flaky and cooked through.
Garnish with sesame seeds and green onions and enjoy!
