Brown ground beef and onion. Salt and pepper to taste. Drain grease. Stir together rice and browned ground beef and set aside.
Bring a large kettle of water to a boil and remove from heat.
Carefully remove 16 leaves from the head of cabbage and put leaves in the water and let set until wilted.
Remove a leaf from the water with tongs, take a good sized tablespoon of the hamburger-rice mixture into the leaf and wrap leaf around the burger mixture. May need to secure with a toothpick to keep closed.
Place in a greased 9x13 pan.
Repeat with remaining leaves and burger mixture.
When you have used all the mixture, pour tomato juice and water over top of cabbage rolls.
