Clean the chicken breast and cut it into smaller pieces.

Wash the mushrooms, dry them, and slice them into medium-thick slices.

Heat the butter in a frying pan. After a moment, add the mushrooms and sauté for a few minutes, stirring occasionally.

Then add the meat. Fry until the meat is properly cooked, which takes about 6-10 minutes (depending on the size of the pieces), stirring occasionally.

Remove from the heat and after a moment, add the yogurt. Season with salt and pepper to taste and mix thoroughly.

Transfer to a plate.
