Wash and cut the cherry tomatoes in half.
Salt and pepper the pollock on both sides and place it on foil. The piece of foil should be one and a half to two times larger than the fillet.
Make a kind of boat for the fish from the foil. Transfer to a baking dish.
Place the tomatoes and pour in the cream, sprinkle with spices.
Preheat the oven to 200 degrees. Put the fish in the oven for 30 minutes.
Serve with arugula and cherry tomatoes.
