Preheat the oven to 400°F (200°C, or gas mark 6) and place the rack in the middle of the oven.
In a small bowl, make the teriyaki sauce by whisking together the coconut aminos, apple cider vinegar, honey, garlic and ginger (see note).
Season the salmon fillets with salt and pepper on both sides. Place the salmon fillets skin-side down in a baking dish. Pour the teriyaki sauce over the salmon, making sure to coat each fillet evenly.
Bake the salmon for 10 to 12 minutes or until it’s cooked through and flakes easily with a fork.
Meanwhile, heat the olive oil in a large skillet over medium-high heat. Cut the bok choy into quarters and add to the skillet. Season with salt and pepper and sauté for 5 to 7 minutes or until the bok choy is tender and lightly browned.
Divide the bok choy among four plates and top with a salmon fillet. Sprinkle with sesame seeds and serve.
Notes
To make this recipe spicy, add ¼ teaspoon of chile flakes to the teriyaki sauce.
