Processing a cabbage

It's harder than it seems.  I bought a cabbage to try out a braised cabbage and sausage recipe, which was great, but then found myself with scads of leftovers.  For next time, here is my plan for using a cabbage in a one person GAPS household:

Outer third - GAPS cabbage rolls, which I would cook, freeze, and bring to work for lunches.  I still need to come up with a good substitute for rice to soften up those little rolls of ground beef...perhaps cauliflower?

Middle third - shred using food processor for sauerkraut.

Inner third - braise or boil for an immediate meal.

This allows me to use a large vegetable in a way that (i) makes best use of all of its parts and (ii) not eat the same thing for a week!  Sauerkraut takes a couple of weeks, cabbage rolls can be thawed much later than that, and I have one immediate meal.  This is important to me with regard to cabbage because I am on GAPS because of a thyroid problem.
