Potato peels will make it starchy, and any potato sprouts/green peels should be avoided. Sweet potato peels and squash innards are excellent, as are leek tops. Throwing a bay leaf and clove in adds depth.
I've never tried sweet potato peels. I'll have to start saving those for our next batch!
I usually will also toss in celery tops, a couple peppercorns, and whatever herbs need trimming (basil, oregano, sage, etc.).
