Add salt, egg and flour to potatoes and mix well. Dough should not be thin. More or less flour may be used according to size of potatoes.
Put dough on plate. Use a teaspoon to scrape off small portions at a time and place in boiling water. Boil about 15 minutes. Keep stirring to prevent scorching. Drain in colander. Rinse once with water. Don't let Halushki get too cold, place in bowl.
Brown onion in shortening, add cabbage and fry slowly until browned, about 20 minutes. Pour over Halushki, mix well (salt to taste) and serve hot.
Sift dry ingredients. Cut in butter and shortening. Add 6 - 7 Tbs. water so the dough holds together. Gently knead the dough. Turn onto floured board and roll to about 3/8" thick. Cut into 5" squares.
Preheat oven to 450 degrees. Combine apples, sugar and cinnamon in a bowl. Place 3 to 4 tablespoons filling on each square. Fold into triangle, wet inside edges with a small amount of water. Press edges together and seal with a fork dipped into water. Make 3 slashes in each turnover so steam can escape. Place turnover about 2" apart on a greased cookies sheet. Bake 15 minutes, reduce heat to 350 degrees and bake 15 minutes longer. NOTE: you can frost or glaze the turnover if you want a really sweet treat.
