Turn your oven to 250C (480F). Cut each salmon fillet into 3 chunks. Place on a rimmed baking sheet (I line mine with baking paper). Scatter over coleslaw mix.
Mix soy, vinegar and maple syrup or honey. Drizzle over the salmon.
Pop in the oven. Set your timer for 10 minutes.
If using nori / seaweed sheet, cut finely into ribbons with scissors.
When the timer goes check the salmon is cooked to you liking. Divide between two bowls and top with nori or sesame seeds.
