Prepare the pork. Fry the meat in vegetable oil in a frying pan until golden brown, stirring occasionally. Transfer the cooked pork to a separate plate.
Now let's get to the mushrooms. Fry the champignons and onions in the same oil. Add the meat and pour in the water. Simmer over low heat for 10 minutes. Add salt and pepper. After cooking, let the dish sit for 5-7 minutes.
