To make the cheese sauce  Put the butter, flour and milk in a saucepan and heat gently until the butter has melted and the sauce begins to thicken. Constant stirring is necessary here otherwise lumps will form.  Season with salt and pepper.  Once the sauce has thickened to the desired consistency, take off the heat and stir in three quarters of the grated cheese.  Poor this mixture over the top of the fish and prawns.

Topping  Spoon mashed potato onto the top of the fish and sauce mixture and smooth out a little.  Sprinkle the remaining grated cheese over the top of the mashed potato.  Bake in the oven, 180 Celsius, for around 30 minutes or until the top is golden and crispy.  Serve with peas and sweetcorn or any vegetables of your choice.
