This pie consists of a flaky crust and it is filled with the most flavourful fish filling.
To make the filling, pour half of the oil from one can of sardines into a skillet. Let it heat up on medium heat then saute the onions until fragrant. Add in garlic and stir then add in the green onions and carrots. Mix until well combined then you push the vegetables to one side of the pan. Put in all the sardines without the oil into the pan. Then mash them, being careful not to make it too mushy. Mix the mashed fish together with the sauteed veggies and turn off the heat.
To make the dough, combine flour, butter, salt and baking powder in a bowl. Mix using your fingers until the mixture looks like breadcrumbs. Add the cold water and mix to form a dough.
To make the pie, roll out about 1/8th of the dough and place on an open large hand pie maker. Put in two tablespoons of the filling. Then press the hand pie maker together to seal the edges. Repeat process wth the rest of the dough. If you do not have a hand pie-maker, simply roll out the dough into a large rectangle then use something with a round edge like the lid of a small pot to form circles on the dough. Place your filling in the middle of each circle then cover to form a half moon. Press the edges with a fork so they seal.
Place pies on a baking tray lined with parchment paper. Beat an egg then use a pastry brush (or your hands) to rub the egg all over the pies.
Bake in an oven at 350 degrees F (180 degrees C) for 20 minutes.
