In a large bowl, combine miso paste, coco aminos, sesame oil, sambal oelek, ginger and hot water. Whisk until well combined and smooth. Reserve 2 tbsp of marinade to the side.
Add salmon filets to the bowl with the marinade and gently toss making sure salmon is well coated. Place in the fridge and marinade for 1-2 hours.
Preheat oven to broil and make sure the rack is about 6 inches away from the heating element.
Put the salmon on a foil lined baking sheet and place in the broiler for 1 minute. Remove the salmon and brush with reserved miso marinade.
Broil for another 2 minutes and then brush again with remaining miso marinade.
Broil for another 3-4 minutes or until cooked to your liking.
While the salmon is broiling, preheat a medium skillet over high heat.
Add avocado oil and once the pan smoking, add the baby bok choy cut side down. Don’t touch the baby boy choy and let it sear for 2 minutes.
Once the baby bok choy is charred, flip over and add the garlic and season with salt. Add more oil if necessary.
Quickly add 6 tbsp of vegetable broth (or water) and cover with a lid and turn the heat down to low. Steam for about 3 minutes until the liquid has evaporated.
To serve, place rice in a shallow bowl or plate, top with charred bok choy, salmon and garnish with sesame seeds and scallions.
