In a medium bowl, mix together chili garlic sauce, mirin, vinegar, soy sauce and 2 teaspoons sesame oil. Pour over salmon in a shallow baking pan and marinate 10 to 15 minutes. Flip and marinate 10 to 15 minutes more. Preheat oven to 400° F.

Spray a large oven proof skillet with cooking spray and heat over medium high heat. Remove salmon from marinade and sear 2 to 4 minutes. Flip over salmon, transfer to the oven and bake for 8 to 10 minutes.

While salmon is baking, cook noodles according to package directions. Drain well and toss with green onions, sesame seeds, salt and remaining 2 teaspoons sesame oil. Divide noodles between four plates and top with salmon.
