Cranberry Sweet Potatoes

This was part of the Resnick/Rosen/Teutsch Thanksgiving, Shulamit's very first. She was considerably smaller than the turkey.
What I like about this dish is that the colors are really beautiful. Would be nice for a vegetarian potluck - it is vegan/gluten free and both yams and cranberries are extremely nutritious superfoods.
For the 1323 feast, I used freshly cooked cranberry sauce, though the recipe calls for canned.  It is so easy to make, and so much better, but not essential - canned is fine.
It is easily doubled.
I clipped it out of a newspaper decades ago. The onion is an interesting addition.

Note, I don't microwave the yams first.  With a Santoku knife they are not that hard to cut.
