Beef Wellington Appetizers

Preheat oven to 425 °F (220 °C) . Cut sirloin steak into 1/2 x 1-inch pieces. Marinate in teriyaki sauce for 1 hour. Prepare a two crust pie shell dough; roll into two 9 x 12-inch rectangles, then cut into 2 x 3-inch strips. Finely grind chicken livers until smooth. Divide over each steak piece then place the steak piece on a pastry strip; fold to enclose and seal the edges. Brush with beaten egg and place on a greased baking dish. Bake for 20 minutes.
