2) Add the tomatoes and bring to a boil. Reduce the heat to medium-low and allow to simmer for about 5 minutes, until the tomato juices thicken.
3) Remove from the heat. Stir in the parsley, dill and prawns, and season with salt and pepper. Sprinkle the feta over the top. Bake until the prawns are cooked through and the cheese melts, about 12 minutes.
