To make the pastry, combine the flour and salt in a large bowl.
With gloves on, grate the butter into the flour.
Using a pastry blender, cut the butter into the flour until evenly distributed.
Make a well in the center of the flour.
Add beaten eggs in the middle.
Slowly add the flour into the center and mix until you have a shaggy dough.
Add water, a little at a time. Add just enough water so that the dough comes together.
Wrap in plastic wrap or a ziploc bag and place in the refrigerator for at least ½ hour.
Meanwhile, make the filling.
In a large cast iron skillet, heat oil.
Add onion, bell peppers and celery.
Saute until it starts to change color.
Add garlic and tomatoes and cook for 5 minutes.
Add capers, raisins, ketchup, mustard, Worcestershire and sambal.
Stir to combine and cook for 1 minute.
Add tuna fish. Break up the tuna and cook for another 2 minutes.
Add parsley and stir to combine.
Add salt and pepper. Stir to combine.
Let it cook for a few minutes.
Using a rolling pin, roll out the dough to a circle as thin as possible. Work with half of the dough at a time.
Using a 5” biscuit cutter, cut out circles from the dough.
Place about 2 tablespoons of the tuna filling on each circle.
Brush the edges with water.
Seal the pies by pressing the edges together.
Crimp the edges with a fork or twist the edges to seal.
Repeat until all the pastry dough has been filled.
Heat a deep pot with oil.
Place the tuna pies in the hot oil and fry until golden brown on both sides.
