Poppy Seed Squares

Directions

1. In a large skillet, cook the beef, mushrooms and onion over medium heat until meat is no longer pink; break into crumbles. Add the soup, horseradish, salt and pepper. Remove from the heat; set aside.
2. In a large bowl, combine the flour, poppy seeds, baking powder and salt. Cut in shortening until the mixture resembles coarse crumbs. Gradually add water, tossing with a fork until a ball forms. Divide dough in half. Roll out 1 portion into a 15x10-in. rectangle; transfer to an ungreased 15x10x1-in. baking pan.
3. Spoon meat mixture over crust. Roll out the remaining dough into 15x10-in. rectangle; place over filling. Bake at 425° until golden brown, about 25 minutes. Cut into 96 squares.
