Season the fish filet with salt & pepper and fry it till golden and crunchy,

Chop tomatoes, onions, garlic and green onions (you can just chop it as you want),

In another pot, fry the onions until translucent then add the garlic,

Fry the shrimps with the onions and garlic then season with salt and pepper,

Once the shrimps are orange, add the chopped tomatoes, 1 spoon of canned tomatoes, 1 teaspoon of curry powder and if you want to spice it up, a bit of red chili powder,

Once the tomatoes are soft, add the coconut milk, rectify the seasoning with a bit of salt and pepper if necessary and add the green onions. Add water if you consider that the sauce is too thick. Finally, add the fried fish at the end to not have it smashed (I made the mistake of adding it early! :D :D)
