How to make
Knead a smooth dough from the listed products and divide it into two parts. Fry the chopped onion in a little butter and add the crumbled meat, mushrooms, spices and chopped eggs. Spread one ball of dough on the bottom and walls of a buttered tray.
Add the filling on top. Wrap the pierogi with the second ball of rolled out dough, which needs to be the size of the tray. Pinch the edges of the two crusts together with your fingers.
Put the chicken pierogi to bake in a moderately heated oven until browned. Spray the baked Kiev pierogi with water and smother with a towel.
