Golabki ("golumpki") - cabbage rolls

Mixture of cooked rice, fried ground beef, bell peppers, and onions, and Grandma maybe used cumin, too, rolled into a ball a little smaller than a hard baseball and surrounded tightly by one to two boiled cabbage leaves (hard stem edges cut off).  Place leftover/unused cabbage leaves in oiled baking pan, place golabki on them, then cover golabki only with favorite tomato sauce.  Bake at maybe 350 for 30-40 minutes.  Haven't made these in maybe 20 years, but realizing I loved Grandma's, and my daughter Angie could eat this.  Wikipedia has "golabki," and one recipe says pour beef broth instead of tomato sauce.  I personally liked how the tomato sauce thickened on the rolls.  Maybe use both?
