One of those light healthy meals that can be made in next to no time at all. Needs any white fish, tomatoes (tinned or fresh, chopped), herbs (chopped parsley + chives is good), grated cheese (gruyere, emmenthal or cheddar is good), a small carton of soured cream, salt & pepper.
Melt a little butter or oil in a heatproof dish, add fish – cut into pieces - & grill for c10 minutes, turning once or twice.
Add the other ingredients to the dish, stir, & grill until all is bubbling.
