I want to say first time making a pie with store-bought puff pastry. This option I did not like. The dough crumbled, the filling barely held it. So the second time made with the dough from the recipe " tart with red onion." http://www.povarenok .ru/recipes/show/131 724/. I enjoyed it so much more, but then the choice is yours. So, roll out the prepared or store-bought dough to fit the form ( I, diameter 25 cm ) subject to the bumpers. The form with the dough put into the fridge.

Fry the sausages with two sides, first plump...

... then thin, I cut them in half, I had a long sausage.

Sour cream mixed with grated cheese, egg, salt and pepper.

Get the form with the dough from the fridge and put in her fried sausages.

Evenly spread the filling and bake in a preheated 200 degree oven for 30-35 minutes, until a nice Golden brown.
