My mom always gives us a Costco spiral cut ham at Christmas, there's just two of us so quite a bit ends up frozen. Knowing that we won't get through all of it, I take off an inch or so off the sliced part and freeze it to start. Then the middle gets eaten. The end part gets chopped up for soup. The pieces for soup I chop first and then squeeze out the air in a freezer bag. I'll freeze the bone until I'm ready to make the soup too, usually just toss it in a gallon sized freezer bag and roll up. Then when I'm ready, I buy the bag of 15 bean (or 12 or whatever it is) soup mix and basically follow the directions, or at least the directions of the brand I used back then, it's slightly different now.
