In a large skillet with a lid, brown the ground beef and onion until done. Drain off any grease. Add the shredded cabbage, garlic powder, salt, pepper, butter, and water. Stir well.
Cover and simmer 15 minutes. Remove from heat and allow to cool completely.
Take two of the balls of dinner roll dough and roll into ovals.
Place about 1/4-1/3 cup ground beef filling onto one of the ovals and sprinkle shredded cheese on top and add the other oval of dough.
Continue this until you are out of filling.
Place the filled ovals onto a greased cookie sheet.
Cover with a towel and allow to rise in a warm place 30 minutes.
Bake at 350 degrees F for approximately 20 minutes, or until golden brown.
