Sounds like you have it pretty much covered! With the green beans - it would probably be a good idea to do a "dry run" before Thanksgiving to see how close you can get to the original. It sounds like your mom is fairly set in her ways, and may give you grief if it is too far off. If I were you (and, of course, I am not) I might make a small container of the original (for her, and possibly Hubby), and a larger one of a completely different veggie, non-traditional but LC and delicious. If that went over well than I might consider dropping the bean casserole entirely in a year or two. My family never got into the bean casserole at all (and DH is European, so his only version of Thanksgiving is what I have shown him), so I do our "Must Have", Brussels Sprouts (though not always the same recipe), and some other sort of veggie, whatever looks good at the market.
