For filling: In medium saucepan, combine pumpkin, sugar, and pumpkin pie spice; bring to a boil. Reduce heat; simmer 10 minutes. Stir in nuts. Cool; set aside. For dough: In medium bowl, combine flour, baking soda, salt, and cinnamon; set aside. In large mixer bowl, cream shortening and sugar. Add eggs; beat until fluffy. Add dry ingredients; mix well. To assemble: Divide dough into 3 portions. On floured foil, roll out 1 portion of dough into 8 x 30 cm rectangle (keeping remaining dough chilled). Spread with one third of filling. Starting from wide end, roll as for jelly roll. Wrap in foil. Repeat process with remaining dough and filling. Freeze rolls several hours or overnight. Remove one roll at a time from freezer; unwrap and, with sharp knife, cut into 1 cm slices. Place on greased cookie sheet. Bake in preheated 400-degree oven for 10 to dozen minutes, or until golden. Cool on wire rack. Drizzle with icing. For icing: In medium bowl, combine powdered sugar, butter, vanilla, and milk; blend until smooth. From "Libby's Favorite Pumpkin Recipes".
