Prepare everything necessary. You can take any minced meat. The mushrooms here are wild, and they are already boiled. If using champignons, pre-boiling is not necessary.
Heat the pan, pour in vegetable oil. Put the coarsely chopped mushrooms and one onion. If the mushrooms are boiled, they should be well squeezed from the liquid.
200 g mushrooms, 2 tbsp vegetable oil, 2 pcs onion
Fry over medium heat until the mushrooms are lightly browned and the onions are soft. Add sour cream, salt, and spices. Mix.
2 tbsp sour cream, 1 pinch salt, 1 pinch pepper
Introduce chopped onion (use the second onion), egg yolk, pepper, and salt into the minced meat.
400 g minced meat, 2 pcs onion, 1 pc egg, 1 pinch salt, 1 pinch pepper
Mix with hands, and then slightly beat the minced meat so that the mass is compacted and the finished products retain their original shape.
Roll the minced meat into balls the size of a chicken egg, then make a depression in the center with your hands, leaving a thin layer of minced meat at the bottom and side walls. Fill with mushroom filling. Sprinkle with grated cheese.
