In a large bowl, combine 1 1/2 cups of flour, sugar, yeast, and salt.

In a small saucepan, heat milk, water, and butter until warm (120-130°F).

Add the warm liquid to the flour mixture and beat until smooth.

Add eggs and remaining flour to form a soft dough.

Knead dough on a floured surface until smooth and elastic, about 6–8 minutes.

Place dough in a greased bowl, cover, and let rise in a warm place until doubled, about 1 hour.

In a large skillet, heat oil over medium heat. Add ground beef and onion, cooking until beef is no longer pink.

Stir in cabbage, salt, pepper, and Worcestershire sauce. Cook until cabbage is tender. Remove from heat and let cool.

Punch down dough and divide into 8 equal pieces. Roll each into a 6-inch circle.

Place about 1/3 cup of the beef mixture in the center. Fold dough over filling and pinch edges to seal.

Place runzas seam-side down on a greased baking sheet. Cover and let rise 20 minutes.

Preheat oven to 375°F. Bake for 20–25 minutes or until golden brown.

Remove from oven and brush with melted butter. Serve warm.
