White fish with coconut sauce and mixed pepper couscous

This works well with any white fish fillet; I used basa. I also had some leftover beansprouts in the fridge so I used them as well.

Recipe
Preheat the oven to 200C/400F/Gas 6.
Place the white fish fillet onto a sheet of aluminium foil, drizzle with the oil and season, to taste, with salt and freshly ground black pepper. Pull the sides of the foil together to form a parcel and fold to seal well. Transfer the parcel to a baking tray and bake in the oven for 15-20 minutes, or until the fish is opaque and has cooked through.
Prepare 2 peppers, dicing them, and make up 50g cous cous in a lidded saucepan, adding half of the diced peppers, 2 tbsp olive oil, 1 crumbled chicken stock cube, salt and pepper and just enough boiling water to cover the cous cous. Set aside for 10-15 mins.
Fry the rest of the peppers and 2 chopped spring onions in a pan of melted butter, and add 1 tsp ginger. Add some frozen peas too. Then add 200ml coconut milk and simmer.
To serve, remove the lemon sole from the foil and place it onto a serving plate. Spoon the mixed pepper couscous alongside, then drizzle everything with the coconut sauce.
