Heat rapeseed oil in a skillet over medium-high heat. Fry the fish fingers for 3-5 minutes until golden and crispy. Set aside.
Wash the tomatoes and cut them into small cubes. Slice the spring onions into small rings.
If desired, briefly pre-cook the rice for about 2-3 minutes. In a bowl, combine the rice with the tomatoes, spring onions, cremefine, and Mediterranean spice mix. Mix well.
Grease a baking dish and spread the rice mixture on the bottom. Arrange the fish fingers on top. Sprinkle with the grated cheese.
Bake in a preheated oven at 200 °C (392 °F) for 20 minutes.
