For the marinade: Combine all the ingredients in a bowl. Place the salmon pieces in the marinade and coat. Leave for at least 20 minutes, but a few hours is ideal.
Bring a large saucepan of water to the boil. Add the soba noodles and cook for 3 minutes (or according to packet instructions). Drain and set aside.
180 g soba noodles
Place a large frying pan over medium heat. Add the salmon pieces and cook each side for about 3–4 minutes (or to your liking). Remove and set aside on a plate. Wipe out the pan if charred.
Place the same frying pan back over high heat. Add the oil and let it heat. Add the mushrooms and cook, stirring, for 2–3 minutes until they colour. Add the broccolini and stir through for 2 minutes. Then add the snow peas and sauce to the pan and stir over high heat for 1–2 minutes. Stir through the edamame beans, then turn off the heat. Add the soba noodles and gently stir through the sauce.
1 tablespoon peanut oil, 1 cup mushrooms, 1 bunch broccolini, 1 cup snow peas, 3/4 cup edamame beans, 180 g soba noodles
Serve the soba noodles in bowls. Add the cooked salmon pieces and sprinkle over some sesame seeds.
