In a large bowl, stir together sugar, yeast, salt, olive oil, milk, and hot water. Add 1 1/2 - 2 cups of flour and stir until smooth.
Add enough flour to make a soft dough that doesn't stick to your finger.
Dump the dough out onto a lightly floured counter and knead a few times until smooth.
Place dough in a bowl that has been sprayed with cooking spray. Cover with plastic wrap and let rise in a warm place until doubled, about 60 minutes.
While the dough is rising, prepare the filling.
Brown the ground beef in a large skillet over medium-high heat. Add the diced onion and cook for another 7-8 minutes. Drain off any excess grease.
Add the garlic and saute for another minute. Stir in the seasoning salt, pepper, and Worcestershire.
Add the water and shredded cabbage. Cook and stir over medium heat until cabbage is crisp tender.
Preheat your oven to 375°. Line a baking sheet with a silicone liner or spray it with cooking spray.
Punch down the bread dough and divide it into 8 equal pieces.
Press each dough ball into a circle about 6 inches across. Place 1/2 ounce of cheese in the middle. Top with about 1/2 cup of meat mixture.
Press the sides of the dough together and pinch together to seal. Place seam side down on the prepared cookie sheet.
Bake at 375° for 18-20 minutes, or until golden brown.
If desired, brush the tops of the runza sandwiches with melted butter.
Serve hot. We like to serve ours with fry sauce or ketchup.
