I have to take a side dish to a potluck on Saturday, and the following
keeps tapping me on the shoulder as an idea:

Visualize it, Sicily 1932... No, no.. That's Sophia from Golden Girls.
Let me try again...

In my mind's eye I see a baking dish with overlapping slices of onion,
apple, and sweet potato. I think I've seen this dish before, but I
can't remember where, and I'm trying to figure out how to achieve the
image in reality.

Can I just layer them in raw and bake them? Put on some stock? I
know... apply stock and cover for the first part of cooking, then remove
the cover (tin foil) to allow the stock to evaporate and the slices to
brown up a bit? 350F for 40 minutes and then 400F for 20 minutes?

Herbs? Maybe fresh thyme? Sprigs scattered around. Veggie stock so I
can honestly say it's a veggie dish. (Many vegetarians at the potluck,
although plenty of carnivores, too.) Too bad, because I have some
amazing chicken stock on hand. It would taste better with chicken
stock... hmm...

Vidalia onions maybe? I have Granny Smith apples.
