In a small bowl, mix sesame oil, coconut aminos, grated ginger, garlic, and sesame seeds.
Place salmon fillets in a shallow dish and pour half the marinade over them. Let them sit while you prep the veggies.
Heat avocado oil in a large skillet over medium heat. Add mushrooms and cook for 3–4 minutes until they start to brown.
Add bok choy to the skillet with a pinch of salt and cook for another 3–5 minutes until tender but still crisp.
Remove veggies from skillet and set aside. In the same skillet, place the salmon fillets skin-side down. Cook 3–4 minutes per side until flaky and cooked through.
Drizzle remaining marinade over salmon before serving.
Serve everything in containers for meal prep or plate it up hot and fresh.
