Fish cleaned and well washed. Add in sour cream, salt, lemon juice and favorite spices for the fish and properly RUB this mixture of fish to Put in the fridge for two hours.

Onion peeled and cut chetvertfinalny. I have already cooked wild mushrooms, they are more aromatic and more intense flavor, but you can use mushrooms.

In vegetable oil fry the mushrooms with onions. Season with salt and pepper. To give the filling cool.

Put the fish on the foil. In the belly of the fish put the mushroom stuffing. Skalyvaniem tummy with a toothpick to keep the stuffing from falling out.

On top of the fish lay overlapping thin slices of tomato and a plate of cheese, alternating them. Lightly wrap the fish in foil, forming the sides (to allow the juice to stand out, remained in foil, not burning in the form), but not tightly covering the top, so the cheese will melt, sticking to her. Put in preheated oven for 20-30 minutes (depends on oven).
