Preheat the grill to high. Toss the cucumber in a bowl with the vinegar; set aside while you prepare the rest of the ingredients. Put the salmon fillets on a foil-lined baking tray and spoon over 1 tbsp teriyaki marinade. Put under the grill for 8-10 minutes until cooked through.
Meanwhile, tip the edamame into a large saucepan of boiling water and simmer for 2 minutes. Drain in a sieve and rinse under cold water; set aside. Rinse out the saucepan and refIll with boiling water; simmer the noodles for 5 minutes. Drain and rinse under cold water, then pat dry on kitchen paper and toss with the sesame oil.
Divide the noodles between 2 bowls. Lift the cucumber from the vinegar and divide between the bowls with the edamame and salmon. Add the remaining 2 tbsp teriyaki marinade to the cucumber vinegar and spoon over the top, then scatter with the salad onions and sesame seeds to serve.
Cook’s tip
Buckwheat soba noodles have a lovely nutty flavour and are wheat-free, but you can replace them with rice, egg or udon noodles in this recipe.
