Finely chop and fry in a pan onion.

Blue peel and cut into cubes (the size of dice). If a lot of seed (seed)- to clean as possible. Add to fried onions and fry all together. Season with salt and pepper. You can add mushroom bouillon cube, but then do not add salt. When cooked through blue - protushitsya, in General, it becomes soft, add the sour cream to put out another 3-5 minutes.

RUB cottage cheese on top and cover with the lid. Turn off the heat. It turns out very similar to a julienne. Bon appetit. PS In the picture the blue is not brushed - it is the first time did. Then remade with clean – much nicer texture turned out.)))
