Step 1

Preheat oven to 425°F. Line 9 inch pie plate with pie crust.

Step 2

Heat oil over medium-high heat in large skillet. Add ground beef and start to break up with wooden spoon. Cook ground beef for 7-10 minutes, or until beef is browned. Drain the excess liquid.

Step 3

Stir in breadcrumbs, tomato sauce, onion, green pepper, garlic, salt, oregano and black pepper. Cook until everything is warmed through, about 1 minute. Pour beef mixture into pie plate, making an even layer.

Step 4

Beat together the milk and egg. Stir in Worcestershire sauce, salt, dry mustard and cheese. Spread the cheese mixture evenly on top of the meat.

Step 5

Bake for 30 minutes or until cheese and pie crust is golden brown. If pie crust is starting to brown too quickly, cover the crust with aluminum foil. Let cool for 5 minutes before serving.
