I do mine with chicken breast but this can be changed to fish instead.
Fish/cod or whatever fish you like
1 onion finely chopped
2/3 carrots
2/3 courgette
2 peppers [red/greenyellow whatever you have)
some mushrooms
tin of chopped tomatoes
garlic
stock cube
white wine optional (i prefare to drink this)
small carton of single cream.
Fry onion until soft, chuck everthing else into the pot EXCEPT cream and fish. I usually only add about 1/4 pt water to the stock cube as otherwise it can be too liquidy when you add the cream. Bring to the boil and simmer for about 25 mins then add the fish dont cut too small as it will break up. Leave to simmer for about another 10 mins check if carrotts and fish cooked, when they are add the cream and stir ready to serve about 5 mins after cream added. I usually have this with new potatoes or rice.
Hope you like it
