In a mixing bowl, combine flour and salt. Cut in cold butter until the mixture resembles crumbs.
Add cold water gradually and mix until a dough forms. Wrap in plastic and refrigerate for 15 minutes.
In a skillet, heat oil and cook ground beef until browned. Add onion, potato, carrots, peas, and spices. Cook until vegetables are tender. Let the filling cool.
Roll out the dough and cut into circles. Place filling on each circle, fold over, and seal edges with a fork.
Brush pies with beaten egg and fry in hot oil until golden brown and crispy.
Notes
Serve warm. You can bake the pies at 375°F for 20 minutes instead of frying for a lighter version.
