Brush the salmon fillet with 3-4 tbsp of teriyaki sauce, keep for 30 minutes and then pan-fry. (The original method suggested baking the fillet at 200°C for 10 minutes but I chose to pan-fry the fillet). Break the salmon into bite-sized pieces and keep aside.
Trim the snow peas and thinly slice lengthwise. Keep aside.
Boil water in a large pan and cook the soba noodles for 4 minutes or based on packet instructions. Drain and keep aside.
In a large wok, combine the snow peas, noodles, remaining teriyaki sauce, rice wine vinegar, sugar, sesame oil and salt to season. Toss well on high heat for a minute and remove from flame.
Add the salmon pieces and sprinkle with toasted sesame seeds.
