All the necessary ingredients

In minced chicken add boiled buckwheat (not seethe!) mixed with butter. Buckwheat should not be hot. Add to the same raw egg, onion chopped (in a blender), salt, pepper, favorite preservatives to taste. All thoroughly kneaded.

Let the meat rest in the fridge and prepare the filling. For the first filling of boiled eggs finely chop and mix with chopped green onions. Salt to taste. For the second filling, finely cut mushrooms and onion, grate carrot on a small grater and fry all in sunflower oil. At the end add cheese and mix. Salt and pepper again to taste. To a wet Board form our patties. The pellet from minced meat, put the stuffing, wrap it neatly, well fastened.

Coat in breadcrumbs and fry in sunflower oil until Golden brown. It turned out 14 meatballs. In a pan add water (broth) and simmer until tender. Take out patties. In a pan add sour cream, tomato paste, herbs, spices, and if needed more water, all warmed up for 2-3 minutes. We put in our sauce meatballs and heated for another 5 minutes.

Get the result. May be not enough step by step photos, I tried to compensate for detailed description. Bon appetit!!!
