Prepare the "dough" for the chicken meatballs. Finely chop half an onion and cloves of garlic. Add them to the minced chicken along with salt and pepper.
Heat a frying pan with vegetable oil. Form meatballs, fry them for 2-3 minutes on each side until golden brown.
To make the mushroom sauce, finely chop the remaining half of the onion. Melt the frying pan with vegetable and butter, fry the onion.
Cut the mushrooms into thin slices, add them to the onions in the pan, fry until golden brown.
Add sour cream, salt, pepper and water to the pan, stir and bring to a boil. Transfer the meatballs to the pan with the sauce, cover and simmer for 15 minutes over low heat. Add the bay leaf 3 minutes before the end of cooking.
Place the meatballs on a plate, pour the sauce over them and garnish with herbs. Enjoy!
