1. In a large mixing bowl, combine 1 cup of flour and yeast.
2. In a saucepan, heat milk, sugar, butter, and salt until warm (120°F to 130°F).
3. Add milk mixture to flour mixture; add eggs. Beat with an electric mixer on low speed for 30 seconds, scraping bowl constantly. Beat on high speed for 3 minutes. Stir in remaining flour to make a soft dough.
4. Turn dough onto a floured surface and knead until smooth and elastic (about 6 to 8 minutes). Place in a greased bowl, turning once to grease surface. Cover and let rise in a warm place until doubled (about 1 hour).
5. For filling, in a large skillet, cook ground beef and onion until meat is brown and onion is tender. Drain fat. Stir in cabbage, salt, and pepper. Cook and stir for 2 to 3 minutes or until cabbage is wilted. Remove from heat and cool slightly.
6. Punch dough down. Turn onto a lightly floured surface. Divide dough into 16 portions. Roll each portion into a 6-inch circle. Place about ¼ cup filling on each circle. Fold dough over filling and pinch edges to seal. Place on greased baking sheets.
7. Bake in a 375°F oven for 20 to 25 minutes or until golden brown. Serve warm.
