First of all, we cut the meat into cubes with a face of 2-4 cm and toss it in a frying pan over medium heat. We wash the mushrooms, pour boiling water from a freshly boiled teapot . Bring to a boil and cook for 10 minutes. Do not forget to stir-turn the meat so that it is fried evenly and does not burn to the pan. When the mushrooms are boiled, drain the water from them, pour into a container and cool. And then we shred them into small parts; Pour the cut mushrooms into the meat, which is already well fried, add seasoning and mix. Add a good spoon of tomato paste and mix again. Next, spread the processed cheese and mix it thoroughly and melt, the longer and more thoroughly, the better.
