Mix salt and flour. Add shortening and when mixed well, add water and knead until well mixed. Divide into balls about fist size, and wrap in bundles of two each in foil. Freeze extras. Filling for each pasty: 1 cup diced potatoes (raw), 1/4 pound cooked ground or diced meat, 1/4 cup diced onions, salt and pepper. Roll dough into oval shape about as thick as pie crust. Place diced potatoes on dough into a pile. Put ground meat on top of potatoes and then put diced onions on top of the meat. Salt and pepper to taste. Pull sides of dough together and pinch together in a seam. Place on slightly greased pan and bake in 350 degree oven for 1 hour. Can be served with a cream of brown gravy if desired.
