Preparing the "stuffing".
Dice the tomatoes and cucumbers. Separate the grain from the head. Cheese grater on a large grater. Add to the prepared ingredients with the sour cream, stir. Stuffing is ready. I do not salt it, I have enough salinity from cucumbers and cheese (I have sour cream), You look to your taste.
Chicken fillet cut in half lengthwise.
Beat the meat.
Spread in a greased with vegetable oil form, salt the fillets and add pepper to taste.
On fillet uploaded the stuffing. Cover with foil and send in a preheated 180 degree oven for 40-50 minutes (look at your oven, I have only the lower heating).
For 10-15 minutes until cooked remove the foil and cook without it.
