Kidneys in the Trans-Ural style

Soak and clean the kidneys, dry them, and slice them. Place in a saucepan or deep skillet greased with oil.

Wash the tomatoes, slice them, and fry in heated oil.

Fry the mushrooms and potatoes in vegetable oil.

Add tomatoes along with mushrooms, onions, and potatoes to the kidneys.

Salt and pepper to taste, pour with boiled sour cream, and simmer on very low heat until cooked.

Garnish with greens before serving.
