Preheat oven to 425 degrees F (220C). Line a baking sheet with parchment paper.

Defrost the puff pastry, if needed, and unfold it onto a floured surface. Cut each pastry sheet into three pieces on the fold lines.

Whisk an egg in a large bowl. Add sausage, breadcrumbs, parsley, thyme, onion and garlic powders, salt and pepper. Mix together until fully combined.

Divide the sausage mixture into 6 balls. Roll each sausage ball into a long rope and place it down the center of each piece of puff pastry. Roll the dough over the sausage and secure the seam. Turn the rolls seam-side down on a cutting board. 

Beat the remaining egg in a bowl with the water. Brush the egg wash onto the rolls with a pastry brush. Cut the rolls into 6 to 8 pieces each. Place the pieces on the baking sheet.

Bake for 15 to 20 minutes, until puffed and golden brown. Serve hot.
