Preheat broiler and oil the bottom of an oven-safe dish. Cook noodles according to package directions, drain, and drizzle with sesame seed oil to prevent them from sticking together. Whisk the honey and soy sauce in a small flat dish. Place salmon in the honey-soy mixture, turning fish to coat both sides. Let sit for 5 minutes.
Remove the salmon from the honey-soy mixture and place in the oiled baking pan. Broil for 6-7 minutes, until cooked. Reserve any leftover honey-soy mixture.
Heat a large skillet over medium-high heat. Add sesame seeds and toast for about 1 minute until golden brown (the seeds can burn very quickly so keep an eye on them). Remove the seeds from the pan and pour into a bowl. Heat coconut oil in the pan. Add the green onions, bell pepper, spinach, and noodles and saute for 3-4 minutes. Pour in noodles and any remaining honey-soy mixture and toss until noodles are heated through. Add a teaspoon or so of soy sauce if needed for flavor. Serve noodles and vegetables with salmon and sprinkle with sesame seeds.
