Preheat oven 350 degress farenheit.

Slice sausage in half.

Put the sausage on the puff pastry (sliced sausage should be placed next to each other or half overlapping the other slice, in this way the sausage cooks faster) then roll. Stretch the pastry slowly if it doesn't cover all the sides.

Seal the edges. Repeat with the rest of the sausages.

Brush each roll with beaten egg.

Place all the rolls in a baking tray with baking sheet. Bake till it turns golden brown.
