Filling
Brown and drain the hamburger, steaming for 10-1 5 minutes. Mix the onions, butter, water, and drained cabbage or sauerkraut, and combine with the hamburger.
Mix well all ingredients and add to hamburger mixture; cool.
Dough
Dissolve yeast in warm water. Let stand 5 minutes. Add sugar and salt. Beat eggs. Add 2 cups flour and mix well. Add 5 cups flour and melted shortening alternately with the yeast mixture. Let the dough rise until double. Roll dough thin and cut into pieces - put 1/2 cup filling in each dough piece and seal tightly. Bake 350° for approximately 20-25 minutes. Freeze well.
