1. Put pasta shells in a large pan of boiling water and cook till soften. Drain and set aside.
2. Heat olive oil in a large frying pan. Sear the salmon slices and the tiger prawns quickly to seal in the juice and bring out the colour and flavour. Drain and set aside.
3. With the same pan, sweat the onion and garlic without browning. Add in peppers and mushrooms. Fry for 1 minutes. Sizzle in the white wine. Add in the milk and the grated Cheddar. Bring to the boil. Simmer gently till the cheese is melted.
4. Thicken the sauce with blended cornflour with 1 tablespoon of water. Season the sauce with salt and pepper.
5. Break the seared salmon into big chunks. Add the salmon and prawns to the cheese sauce. Heat through.
6. Stir in the prepared pasta and the fresh herbs. Heat through.
7. Serve hot. Garnish with shavings of Parmesan cheese and chopped chives.
