Lightly cook the fish in milk, drain the milk and keep.
Flake the fish into a shallow dish and put on a layer of sliced skinned tomatoes.
Saute a chopped onion, add flour and the milk to make an onion sauce and add about 3oz of strong cheddar.
Pour sauce over the fish/tomato and sprinkle with some grated cheese. Put into the oven and cook till toasty and bubbly on top.
Serve with saute pots and some veg.
