The nice thing about rolling cabbage rolls, is there is no right or wrong. I like to cut the larger leaves in two and make two smaller cabbage rolls. I also use almost every usable leaf of cabbage. Any leftovers freeze well, or you can make them ahead of time and then cook when you want.
Crock-Pot Freezer Meal: You can freeze the cabbage rolls uncooked ahead of time. Do not steam the leaves prior to doing this.
