Ingredients You'll Need
3 loaves frozen bread dough
1/2 cup shortening
3 lbs very lean ground beef
3 medium cabbages, shredded
3 medium onions, chopped fine
1 tbsp salt (I never use salt)
1+1/2 tsp black pepper
1/3 cup plus 2 tbsp butter, melted
Directions
Defrost frozen bread dough according to package directions; let rise once.
Heat shortening (last time I used butter) in large skillet over medium heat. Add ground beef, cabbage and onion. Cook until cabbage is slightly soft, about 5 - 7 minutes; do not brown. Drain beef mixture and stir in salt and pepper; set aside.
Preheat oven to 375ºF.
Roll bread dough into a 12" x 12" square that is 1/4" thick. Cut into 6" squares. Divide beef mixture evenly among the squares; bring corners together and pinch sides shut on each square. Let rise for 20 minutes. Prick gently with fork to allow steam to escape as they bake. Bake for 20 minutes or until brown. Brush tops with melted butter.
