Preparation

• Preheat the oven to 375 degrees. Line a baking sheet with parchment paper.
• In a large skillet over medium heat, saute the beef with onions and garlic, breaking up the meat until it begins to brown and the onion soften, 7 to 10 minutes. Drain some of the fat from the skillet.
• Stir in the Worcestershire, mustard, salt and pepper. Remove from heat, stir in the cheese and set aside.
• Sprinkle a large flat work surface with flour and roll out the pie dough to ¼-inch thick. Use a 4½-inch round cookie cutter to cut 16 circles from the dough, rolling the dough out as needed.
• Place 8 dough circles onto the baking sheet. Place 1½ tablespoons beef filling in the middle of the circles, leaving a ½ inch of dough clear around the edges. Cover each with the remaining 8 dough circles, pressing around the edges of each with a fork to seal. Use the fork to poke a few holes in the top of each hand pie to vent.
• Brush the beaten egg over the tops of each hand pie.
• Bake 12 to 15 minutes, until the edges are browned. Let cool a few minutes before eating.
