Ingredients

• 2 cups milk, lukewarm
• 1/4 cup vegetable oil
• 2 eggs, beaten
• 2 (.25 ounce) packages active dry yeast
• 1/2 cup white sugar
• 1 teaspoon salt
• 6 cups all-purpose flour
• 2 pounds lean ground beef
• 1 onion, chopped
• 1/2 medium head cabbage, chopped
• 18 slices American cheese
• 1 egg, beaten
• 1 tablespoon sesame seeds (optional)

Instructions

1. Preheat oven to 350 degrees F (175 degrees C).
2. To Make Dough: In a large bowl, mix together milk and oil. Stir in eggs, yeast, sugar, salt and 5 cups of flour. Mix well adding remaining cup of flour as necessary to form kneadable dough. Knead for a few minutes, then cover bowl and let dough rise one hour in a warm place.
3. To Make Filling: Brown beef in a large saucepan; do not drain juices. Add onion and cabbage to skillet and continue cooking until onion is soft; add salt and pepper to taste. Let cool.
4. After dough has risen, roll out hunks of dough (about the size of tennis balls) as thin as possible. Place 1/2 slice of cheese on dough, top with filling, then place other 1/2 of cheese on top of filling. Fold over and seal like a turnover (moistening edges with water may help seal them). Place on a baking sheet, brush with egg wash and, if desired, sprinkle with sesame seeds.
5. Bake in a preheated 350 degrees F (175 degrees C) oven for 30 minutes or until golden brown. Serve immediately or cool and freeze for later. To reheat frozen bierrocks simply bake until hot.
