Add the ground beef and cook until it's well browned then add the carrots and potatoes and cook till tender

In a separate bowl, mix the flour and Water until smooth and pour the Flour mixture inside the filling (this will thicken the filling)

Remove from heat and allow to cool

Combine the Flour, Baking powder and Nutmeg in a Bowl and mix well

Add the Margarine and butter (or margarine alone if you choose to) and rub it with the flour until you get a crumbly texture - like Breadcrumbs then begin to add Cold Water, a little at a time until it forms a stiff dough

Transfer the dough to a work surface and knead for 1 minute then place the dough back in the Bowl, cover it with a plastic wrap and place in the Fridge to rest for about 30 minutes

Roll out the Dough to about 1/4 of an inch thick then cut out your desired size circles and scoop about 1 to 11/2 Tablespoons of filling (don't overfill so you can be able to easily close the Pie)

Crack an Egg in a small Bowl, add 3 tablespoons of water and whisk together then use a pastry brush to brush the edges of the Pie

Fold the pie over to seal (and crimp the edge if not using a pie cutter) and use a fork to create a couple of vents on the Pie (this will help prevent air pockets in your pie)

Brush the surface of the Pie with the Egg wash and arrange the Pies on a parchment paper lined tray (You can just rub the Baking Pan with Butter or Margarine as well)

Bake at 350 degrees Fahrenheit for 20 to 30 minutes or till golden Brown.

There you have your fresh Nigerian meat pie. Serve with a cup of hot Tea for Morning breakfast or a chill drink for afternoon or evening snack. Enjoy!
