At "Pie In The Sky", a small cult-ish restaurant/take-out place in Woods Hole, on Cape Cod (near Falmouth, Massachusetts), their sandwiches are available on a considerable choice of breads, rolls, or bagels... or Yorkshire Pudding.

However, theirs are served slightly sweet, and are freshly baked in several batches throughout the morning. And alas, no flavor of beef drippings, which might not work with the sweetness, anyway.

People queue up for them, starting early, or ask when the next batch will be hot out of the oven. So there aren't always a lot "left over" for sandwiches later in the day.

I've never heard of them as "sandwich" type uses elsewhere, until now.
