Portuguese Chouriço Sausage Puffs

1. Chop the boiled egg, and mix both the egg and chouriço with the tomato sauce and season with salt and pepper.
2. Cut the pastry sheets into squares (or desired size) and put a little filling inside each square, without it reaching the edges, so that it can be moistened with some  water, then join the tips.
3. Brush with the beaten egg and bake at 180°C or 350°F until golden brown.

P.S. You can make the filling with any meat or seafood.
