Brown hamburger meat. Meanwhile, wash cabbage, cut up, and place in skillet (I use an electric skillet). Slice up onion, add to cabbage. Drain hamburger meat. Place cabbage, meat and onion in the skillet. Add salt and pepper (to taste).
Meanwhile, follow your hot roll mix directions. When your dough is ready, roll out onto a floured surface to prevent sticking. (Note: when working with the dough I break off some and then roll out.) Next, cut dough into squares. Fill each square with the meat, cabbage, onion mixture. Then fold each corner to center and pinch together. Put the cabbage burgers on a cookie sheet. Cover with a clean towel. Let raise for a few minutes longer. Then place melted butter on each bun.
