I par boil cabbage in a large pan..just enough until I can take apart the leaves. I make some minute rice (about a cup) mix it with onion and hamburg. I put half a can of tomato soup in it with an egg, and squish it all up. I roll it up into cabbage leaves and hold them with a toothpick. I put them in a casserol dish and I pour some tomato soup on top (1 1/2 cans) and bake it about 40 minutes in a 375 degree oven. Everyone seems to like it.
Sometimes, if I'm in a hurry, I cook them in a microwave and put them in the oven just before company comes, to brown the tops.
