In a large skillet over medium heat, brown the ground beef. When the meat is halfway cooked, add butter, chopped onion, and chopped cabbage. Continue sautéing until beef is fully browned and vegetables are softened. Season the mixture generously with salt and pepper to taste. Sprinkle in flour as needed to absorb excess moisture. Allow filling to cool slightly before handling.

Preheat oven to 175°C. Lightly dust a work surface with flour. Flatten each risen dough ball by hand into a round disk, approximately 10 cm in diameter. Place a rounded spoonful of cooled filling in the centre. Gather dough edges and pinch to seal seam. Roll gently to neaten shape. Position seam side down on the parchment-lined tray. Repeat for remaining rolls and filling. Cover with plastic wrap and let stand for 30 minutes.

In a small bowl, whisk together egg and milk to form an egg wash. Brush each assembled roll lightly with the egg mixture. Bake in preheated oven for 18 to 20 minutes until golden brown, rotating the tray halfway through for even colouring.
