To prepare the peppers, remove the tops and reserve. Remove the cores and seeds. Blanch in boiling water 2 minutes, drain and plunge into cold water. Drain well.

Put the fish in a pan with 300 ml (1/2 pint) boiling water, bouquet garni, onion, and seasoning. Cover and simmer for 10 - 15 minutes. Remove with a slotted spoon, remove any skin and bones and flake into chunks.

Heat the oil in a frying pan, add the onion and celery and fry for 2 minutes. Add the rice and fry for 3 minutes.

Stir in the tomatoes, their juice, bay leaf, marjoram, and seasoning to taste. Add 150 ml (1/4 pint) cold water, bring to the boil, cover and simmer for 40 minutes, until the rice is tender and the liquid absorbed.

Remove from the heat. Stir in the fish, prawns and sweetcorn.

Divide the rice and fish mixture between the peppers. Arrange in an ovenproof dish and replace the reserved tops.
